TRYMAG 40Pcs Refrigerator 8x3mm Small Round Magnets for Crafts, Mini Rare Earth Tiny Strong Neodymium Disc Magnets for Whiteboard, Fridge, Office, Hobbies, Kitchen, DIY

These little things are strong!! I purchased these for a parts tray I was printing. I dropped 2 of these into the bed of my tray before the top layers were printed and these things hold on to screws and most tools very well. They are very light and honestly I wouldn't know they were there if they didn't have room to bounce around. I've dropped and stepped on these magnets and they do not chip. They come in a small case so you don't have to worry about them rolling away and sticking to something never to be found again. Definitely worth the buy.

Pretty strong magnets with great quality. Used these in a 3d print project for Mickey Mouse ears for a Disney trip. We're to the right size as described. Never had an issue with the magnet strength, the ears stayed in place the whole time.

The 3 mm thickness is nice for a strong connection. They stay in place pretty well for the size of the magnets. The 6, 8, and 10 mm sizes are a nice combo for various uses and applications. The condition of some of the magnets was slightly concerning. Not many, but a few of them have small defects, dents, or isn't plated right. For the number of magnets you get I can't complain if there are a few defects, however if you want every magnet to be perfect quality and flawless. This probably isn't the choice for you. They also come with a nice plastic case.

Very strong magnets but they were smaller than I expected.

The exact size I needed. The smaller attachments for warhammer utilize this size well.

Arrived on time and in excellent condition!

Very small, not very strong. With the small size they fall out easily and there isn’t much surface to adhere to anything. If you’re looking at these for 3d prints I would suggest finding a different option.

Good quality!
