### ⭐⭐⭐⭐⭐ These are ceramic magnets. Good stuff
*by E***C on January 27, 2026*

Great magnets, useful for glueing to the back of paper towel dispensers and soap dispensers, white boards and more in a metal walled kitchen.

### ⭐⭐⭐⭐⭐ Excellent magnets
*by C***S on December 9, 2025*

Very strong magnets. The dimensions are spot on! I used this for a design project and instead of waiting for them to arrive, like I should, I went ahead and printed my design. These magnets slipped into without an issue.

### ⭐⭐⭐⭐⭐ Strong and various uses.
*by C***Y on November 30, 2025*

These magnets are extremely strong and just what I needed. I have a metal bed frame and bought a dust ruffle that wraps around the frame vs going under the mattress. The problem was the ruffle kept sagging. I placed these magnets around the frame on each side and it holds the ruffle up beautifully!
