GOOBETTER Small Magnet 100Pcs Round Rare Earth Magnets, Tiny Strong Neodymium Disc Magnets for Whiteboard, Fridge, Office, Hobbies, Crafts and Dry Erase Board(4x3mm)

I was surprised by how strong the magnetism was within these tiny magnets. They are well made, very consistent, and a good value. I do wish I could have purchased a smaller amount as now I have a bunch of magnets beyond what I needed.

I bought 100-10mm x 3mm and used them as weights for the edge flaps of a canopy swing cover set. They were nearly always a mess before the magnets. These magnets are as strong as you can imagine. They have a very strong hold on metal and are a real challenge separating from each other.

Many freely available online DIY projects, especially for 3D Printing, use metric sized magnets. Thanks for carrying metric sizes and delivering them so quickly.

I filled up my fridge with pictures in minutes.Highly satisfied and would recommend them...they are small but for the price versus strength...worth it

These may be okay for adults but they are very strong and i had great difficulty in separating them. I bought them for my middle school age boys but with such difficulty they are not good for young people.

they don't hold nearly as well as you'd think they would.

Don't look at the image, thought I was getting a variety of magnet sizes. All one size

picture shows magnets going up to 20mm in assortment. none of these are even 3mm. do not be fooled like me! picture below of biggest one you get. i needed 8mm. and i didnt get it

they said they sent it was never received I'm assuming this is some sort of scam

deceptive marketing, you don't get a variety of sizes, it's all only the tiniest size. they suck.
