Fairly weak magnets especially the smaller size. Magnets are not always securely glued into their casing and can slip out. The colors are cheerful but quality control is low - my large white magnet came out of the package covered in black smudges. These magnets are easy to grab and move/remove making them good for active use. They can be used to create short-term designs display works temporarily or even to complete Lewis Dot Structures on the board. Because they have a weak holding power these are not recommended for long-term displays.
Even the smallest size is good for hanging 8 1/2 by 11 sheets on a magnetic whiteboard which is why I purchased them. These do exactly what I wanted them to.
I like the color variations however the strength of the magnets are lacking. Just to hold one sheet of paper required 3 large magnets. I am not sure what the small magnet are going to hold.
I bought a pack few weeks ago was very useful now I bought a new pack present for my friend family because was very exited when saw mine this product it’s very useful around the house from kids to adults every body can use.
