DIYMAGPowerful Ceramic Round Magnets, 200 Pack with Double-Sided Adhesive, Perfect for Fridge, DIY, Building, Scientific, Craft, and Office Use

These are VERY weak magnets.

Love them!! My grandson is learning about counting coins in class online. It is so much easier if he has hands-on learning. I bought some plastic coins and these magnets and made it so they would stick to his whiteboard with no problem! I saw where some people were complaining because in the picture it looks like the adhesive is already on the magnets. It is not. But I have used other magnets for other things and these have a little tab on the paper to help peel it off!!! Trust me, this is so much better!! It really does go onto things pretty quickly!!

This is great for school projects! I’m going to attach these to glass stones with kids picture on them to be used like refrigerator magnets!

Adhesion to cardboard seems pretty good. But the strength of these small magnets is best used for tiny weights or paper. I decided to use as many as i need to make a few chipboard marble ramps for a sheet metal wall. It takes A LOT OF MAGNETS to hold up a 3" wide (overall) by 24" long piece of 1/8" chipboard. Like 35+ on average. Pictures tomorrow. It would take fewer if the metal wall i am using was dead flat...

I use these magnets to adhere to resin dots to make office and kitchen magnets. They adhere very well and have plenty of magnetizing to stick to refrigerators and metal cabinets. Love this product!
