These are a premium version of the latest craze.
Most have much thinner magnetic strips so they fall apart when trying to use. See picture.
Trust me we went through 8 suppliers before we found ones that were the quality we were after!
Buy all 3 colours to mix and match and do more things with them! That's what happens in our household.
Both Mike and Kai have already stolen several sets of these! Both wander around using them all day lol.
Not a silent fidget, so not suitable, in my opinion for a work meeting or classroom, but a great sensory tool generally.
