Plenty of colours, all really long and last for decent project sizes. Way more than you get from most other suppliers around the same price.

Good quality but doesn’t work with my Flying Tiger 3d print pen, unsure if the pens too cheap or I’m ordering the wrong stuff but I’ll put it to use elsewhere

I bought these to make some replacement board game pieces using an Ender-3 Pro printer. They were one of the few similar products to come in 10m lengths for each colour, which was ideal for what I wanted. Printing with them proved difficult, however, and required a fair bit of trial and error (not all on the colours I didn't need, unfortunately) before I could use them reliably. In the end I needed to go up to 230 deg C and also to keep the fan at maximum in order to get any decent adhesion of the material to itself and stop the parts distorting. The results were then OK for my purposes, but the overall quality of the parts was down on what I've seen with large-reel PLA filament.

Kids enjoyed these filaments. Worked fine

I can't vouch for top quality as my sons 3D robot pen is cheap. It melts fine. My only bugbear was the amount of packaging, all colours were individually wrapped.

Received lot of colours as mentioned. Packaging was okay which came in a big bag. Of course colours vary from what seen on picture but length and count was as expected. I used this with a poloroid 3d pen and worked just fine. As a noob I found it as fun and felt need more practice to get the good shapes. It was drying considerably quick which is much needed for a beginner. It leaves bit of trailers and the end not sure if that is with filament or pen or my experience.

As a large set of varied colours this pack is exactly what I wanted and was well packaged.However, the colours are not exactly as advertised, none of the filament's have colours written on they're packaging and the "transparent" colours are opaque enough that can't be sure which they are.I also definitely have only 3 blue colours and a light wood/sand colour additional.My cheap digital calipers suggested the white length to have a diameter of 1.66 - 1.70 mm, which is a bit off what's advertised, but is reasonably consistent and shouldn't be an issue with pens.

OK so it comes in very generic packaging, however it does contain almost every colour you can imagine.After getting a 3D pen last year I have been looking for a good varied bundle of colours for it so I could make, some really interesting things.This was really good, value for the variety offered. I found a lot of sellers were either offering really small amounts of filimant in colour bundles or large amounts of the same colour.This for me was ideal as it gave a realistic amount of each colour and the amount of colours exceeded my expectation really all the rainbow and more.I'm really looking forward to making loads of new things with it.Our first persuit is to make a forkie off toy story 😂Challenge accepted. Will post pictures when I'm finished.
