### ⭐⭐⭐⭐⭐ Perfect for purpose.
*by A***P on 6 May 2026*

Bought to stick on my fridge so that I can keep track of what's in there. Used with chalkboard "paint markers".

### ⭐ Magnets don’t grip
*by G***E on 14 March 2026*

Pretty much useless… even fridge magnets slide off it

### ⭐⭐⭐ Ok for very light things
*by J***E on 2 May 2024*

I overestimated the magnetic strenght of the item. May be good for very light items / hanging paper notes etc but for storing warhammer models it's not strong enough to keep them in place
