Perfect solution after weight loss.
These ring size adjusters can decrease the ring fit for your finger by .5mm to 1.5mm. They have an almost invisible design. It comes with multiple adjusters of each size. They are very easy to attach to the ring. It is just a clear coiled plastic that goes around the inside hand part of the ring. It can be clipped off to take up as much or as little ring surface as you need. These adjusters seem like they would last a long time. There is also quite a few adjusters that only need a portion of each to use so even if they get to dirty or something you have plenty of replacement pieces. Being that the adjuster is placed on the inside hand part of the ring it seems unlikely much damage would happen to it. I love the convenience of this product. You literally just wrap the coil around your ring and snip off the excess with a scissors. I also love how it’s not some bulky unsightly thing. It’s barely noticeable and that’s only looking at an open hand. Most people would think it’s just part of the ring. The only thing that I think could improve for this product would be some sort of included physical instructions. They include a qr code that requires a special app that I didn’t feel like downloading just for this. I didn’t have sizing instructions but figured it out myself pretty easily. My overall experience was great. I hadn’t worn my actual wedding ring for about 3 years due to losing weight and the ring kept dropping off my finger. I couldn’t justify spending the money to have it resized. I saw this product and the price was more than right to try it. It was so easy to attach to the ring and for the first time in years I’m sporting my wedding band which looks great. I would definitely recommend this product to my Family and friends if they need to shrink their ring size. Anyone who needs either a cheap solution or something to make their ring fit until they can get it resized will love this. This has to be the easiest and least invasive solution.

Not complicated to apply...Inexpensive...and they work great!
As I've gotten older, and I've gotten shorter and smaller in the process. The college class ring I was so proud to wear had begun to spin around on my finger as did my wedding band. I tried tape around the bottom of the rings, but it looked bad and wasn't comfortable. Having then "cut" was going to be expensive and as I get older, would have only been a temporary fix. I found these "curly" clear plastic "thingys" so I decided to try them. They work great! They're easy to put on, and they take on the gold color of the ring! You'd really need to look closely to even see them! They're comfortable, aren't bothered by hand washing or showering and make my rings fit great! They come in multiple sizes and go on relatively easy once you understand how to apply them. Ten minutes of playing with them to get the "hang of it" and I'm back to enjoying wearing my rings again. Another great Amazon prime purchase!

Good product
I lost some weight, but was not ready to get my ring resized. I ordered these in the hopes that the pack would get me through until I decide on resizing. They work great! It took a couple of days for me to get accustomed to it on the underside of my finger. The ring does still rotate and sometimes I have to spin the adjuster into place. I have only used one small piece of of one adjuster. Easy to install and can easily be cleaned while regulary washing hands regulary. There is a a bit of discoloration, but I have been wearing the same one for over six months. It is an excellent value for the price!

The best ring sizers for loose rings - minimal, secure, and comfortable
I love the design if this ring sizer. I looked into spiral types, but I didn't want to see the plastic from the outside of the ring, also it would leave dents in your skin on the inside and outside of your finger. This clip on ring sizer is very minimal but very snug when it snaps on. It comes with several sizes for the width of the ring. The size 4 fit exactly although it was a bit difficult to snap on but once it was one you can barely tell it's on and is SO comfortable! It stays in place too! It turned my ring i couldnt ring to a ring I can wear that fits perfectly. Its clear and no chance of it falling off. Comes with several sizes and is a very good price.

Works well
These ring adjusters are very easy to use. They come in multiple sizes so one is sure to fit your need. They are easy to apply to the ring and stay in place very well. They are soft on the ring so it makes them comfortable to wear. They are clear so they blend into your hand well. The material is a clear plastic. Would buy again.

Fantastic and Versatile Ring Adjuster
Edit to my original review: After wearing my rings with these coils for a couple of weeks, I realized that they have an added bonus benefit. If you are anything like me, your rings (especially solitaires) have a habit of slipping sideways on your fingers and you’re constantly having to straighten them. Once I added these coils to my rings, my rings stay put and they don’t slide around. I love this surprise feature! This package of ring-size adjusters is easy to use, full of enough little coils in multiple sizes to handle a TON of rings, is comfortable to wear, and a great value for the amount of product. Can’t say enough good things about these!

fits right
I bought these to downsize my rings. i've lost weight and now they are too big but in the summer my fingers sometimes swell. My jeweler told me to try these for a while until my weight stabilizes. so far they work great. they are comfortable and easy to apply. the more wraps you put on the thicker they are. they are not sticky or uncomfortable. they are soft and wash easily when you wash your hands. I am more at ease when wearing my rings so i don't accidently lose them. the value is good for the price and peace of mind.

Only two sizes
These ring sizers are easy to install and look good with white gold or sterling. They stay in place well. My only complaint is that there are only two sizes in the pack. If they happen to be the size you're looking for this is a win. If not you wasted your money. They worked on most of my rings, so it was worth the price to me.

Ottimo prodotto
Veramente utili in caso di anelli troppo grossi! Facili da usare e assolutamente discreti, nessuno si accorge che siano sull’anello indossato! Le ricomprerei in futuro anche se nel pacchetto ce ne sono tantissime 😊

Funktioniert sehr gut
Die Ringverkleinerer hatte ich von einer Kollegin empfohlen bekommen. Sie funktionieren bestens und auch meine Haut verträgt das Material sehr gut. Einfach auf den Ring wickeln und passend abschneiden - fertig!

An Easy and Invisible Solution for a Loose Ring
I bought this ring sizer because my new ring was slightly loose, and I wanted a quick, temporary fix without the commitment or cost of resizing. This product arrived on time and has proven to be an excellent, simple solution. I've been using these adjusters for a few days, and they've been fantastic. The spiral design is easy to wrap around the ring band, and it holds my ring securely in place. I love that the package comes with different sizes—this is a huge plus, as I can switch to a thicker adjuster in the winter when my fingers shrink. The Pros (What I Love): Comfortable and Seamless: The clear plastic material is comfortable and doesn't irritate my skin. It's also virtually invisible once it's on the ring, so you don't even notice it's there. Variety of Sizes: The assortment of sizes is incredibly helpful, allowing for a perfect fit for any ring width. Great Value: With 12 adjusters in the pack, this will last a very long time, making it a cost-effective alternative to resizing. Simple to Use: The adjusters are easy to put on and take off, making it simple to get a secure fit. The Cons (What Could Be Better): Minor Discoloration: After a few days of wear, the clear plastic does start to show some slight discoloration. However, given how many are in the pack, it's easy to just swap it out for a new, clean one. This is a very minor issue and doesn't affect the product's function. Overall, this is a great product for anyone with a loose ring who isn't ready to get it resized. It's comfortable, nearly invisible, and provides a secure fit. The variety of sizes in the package makes it a versatile solution. I highly recommend it as an easy and effective fix.

Just the fix I was looking for
Bought the pack of coils + clips and the coils ended up working perfectly for my ring which was just a little too big and resizing would’ve been tough soft plastic doesn’t hurt or feel uncomfortable and so many coils it’ll last you ages even if you switch them out.

Lifesaver
Has literally saved 20+ rings that my partner could no longer wear due to weight loss. Not cheap ones either and resizing would have been very costly indeed. Silicone is comfortable, easy to apply and simple to remove when and if she chooses to in the future for cleaning and such like. Different sizes and varying thickness fits all ring sizes, even some of my more chunky mens rings. The little cloth included for free to clean jewellery is a nice unexpected touch also.
