Review: great product and very strong - These magnets were a life saver to me! I was working on a wearable art piece and needed an easy way for my model to get into the outfit and seal them in. These magnets were magic. I had previously used some that were not strong enough, these were STRONG! Very thick and help through layers of paper. I purchased 2 boxes, one would have plenty. Now I have back up for future projects. Strong Hold, easy to glue to a project and use.
Review: Small but strong - These little magnets are great! They are strong and work great. I am a teacher and I use a white board to write on but I also use it to mount pictures. Our white board is old and wavy in spots so magnets do not hold well but these little magnets holds everything great. We also use them to play a new game where the magnets are in a circle and you try not to let them attach to another magnet. They worked great for the game also. We had fun playing with them Christmas.

## Questions & Answers

**Q: Can these be painted?**
A: I bought them for work and we put colored dot stickers on them. I dont know how well the paint would stick. They have a coating on them already that leaves your fingers black.

**Q: Will these magnets stick to one another ? If so do they hold well ?**
A: Yes the do stick together with a pretty good connection. I have paper between them and the hold a few sheets

**Q: Will opposing sides repel eachother?**
A: grammatical issue 
opposing vs. opposite

**Q: Did anyone ever try to paint these (regular acrylic craft paint)? I noticed someone else asked, but didn't really get an answer.  Thanks for your help**
A: As Steve west said. Clean with soap and water. Use a high bonding primer such as zinnser 123. Or glidden gripper. After primed use whatever paint you want

### ⭐⭐⭐⭐⭐ great product and very strong
*by A***R on January 28, 2026*

These magnets were a life saver to me! I was working on a wearable art piece and needed an easy way for my model to get into the outfit and seal them in. These magnets were magic. I had previously used some that were not strong enough, these were STRONG! Very thick and help through layers of paper. I purchased 2 boxes, one would have plenty. Now I have back up for future projects. Strong Hold, easy to glue to a project and use.

### ⭐⭐⭐⭐⭐ Small but strong
*by O***A on December 25, 2025*

These little magnets are great! They are strong and work great. I am a teacher and I use a white board to write on but I also use it to mount pictures. Our white board is old and wavy in spots so magnets do not hold well but these little magnets holds everything great.

We had fun playing with them Christmas.

### ⭐⭐⭐⭐⭐ Powerful, but the adhesive posed an unexpected, though temporary, problem
*by F***B on February 8, 2026*

These are great magnets. I needed them as a magnetic mount for a device for my car dashboard. I’m not certain, but I think the adhesive needs to set for a time. When I first affixed the magnet to my dash, it came off almost immediately. Then I put it back onto the dashboard, and about two hours later the magnet didn’t move (and hasn’t moved since.) My only issue is the package contains far more of these very good and powerful magnets than I need. I feel there are enough to share with family and friends.
