SPEKS Silver Magnetic Balls

It was amazing to begin with. Its just like putty without the sticky residue. I used it HARD for a couple of weeks and the coating started to peel off (which they do warn you about) once it starts to peel it became annoying to use, it'd create a mess everytime and leave your hands covered in glitter.

I love it. Its really like squishing a high quality bluetak and is great for my fidgeting hands.

My husband loves this one. I could see him focussing on the shape he wants.
