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!!
