Perfect for my project
Exactly what I needed. Small magnets that come with adhesive dots. They are about the size of a dime. Strength is great for holding the wooden spoons as in pictures. For reference, the magnets are placed on the bigger part of the spoon (where the food goes), not the handle.

Out door fun
I need the magnets for some paper mask that will be used out side. To hold it in place on both side I find these to have the strength and capability to do the job. The size was correct and while under the item made the appearance seamless. The value was what I need for the project.

Strong magnet
Works well, convenient, glue sticks very well. I used these on the back of solar lights and stuck them on the side of the van.

Great for perler beads!
Soo the adhesive part is tedious, however I am glad to say they work well for my perler bead crafts. They can definitely hold up like a photograph or shopping list on your fridge, but maybe nothing more than that, possibly a postcard at most if you use 2 magnets on your craft. I did notice while pressing down the magnets to get the adhesive to work- you may get some black pigment on your fingers so be mindful of that

Great assortment!
This kit is awesome. Such variety and the adhesive is 3M and high quality.

Not very strong magnets. Poor adhesive and packing
Alright, description shows magnets with adhesive dots on them in reality, they are crammed into a small box that just barely holds the magnets and most of the adhesive which is small and thin is off tje sheet or bent and exposed. I will be returning these and I needed them for camping tomorrow. They were cheap and I should have known you get what you pay for. UPDATE: the magnets and adhesives are crap . I put 3 magnets on a each of two very light solar lights. These kept sliding off the metal wall that I stuck them to. Adhesive is the gummy stuff and literally comes off of the dot when you try to peel off one side. Im not sending back it aint worth it but im buying something else.

Very Weak Magnets. No use for me.
These are just a waste of money. They are less than N20 magnets. 1mm sheets between will lose their grip. I am very disappointed

Thumbs Up Magnet & Self Adhésive
Just what I needed. Magnet is strong enough for my purposes (but not super strong).

Exactly as advertised
I bought these (along with 5mm magnets from another brand) to sample which would be best for a project I'm working on. For my very specific craft purpose, I will be going with the other brand, but these Trymag magnets are EXACTLY as described and are totally suitable for home/personal use, and I'll be keeping them to use for that. :) In fact, the Trymag magnets might even be manufactured better, as the other brand had quite a bit of surface damage/knicks/gouges, and the Trymag magnets have significantly less. I measured the magnets and they are exactly as described at 0.70 in. in diameter and 3mm thickness. The magnets are decently strong and have no problem holding up my fridge photos. The magnets could maybe be a little stronger, but I'm not using these for large posters or heavy/thick paper or calendars so I can't really say. They seem good enough for my fridge and kid art. What else can I say? Decent magnet, decent price. Came with a bunch of round adhesive backings which I won't complain about.

Not as described.
Magnets are weak, contents dirty, ruining the LOOSE adhesives inside. Magnets do not come with adhesives already fixed to magnets, it's a DIY job and the stickers are likely folded and pinched between the loose packed magnets. Therefore rendering half the pack useless. Packaging is an important part of an item, it can affect the overall item quality and usefulness upon delivery. Picture is not accurate for product, they are matte and not polished or smooth, and again DO NOT have adhesives attached.

Exactly what we needed!
We used these magnets to make our own fridge magnets. They were the perfect size and easy to attach just remove sticker and place. They aren't easy to remove which is a good thing we wanted more of a permanent bond.
