Review: Ok for very light things - 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
Review: Only for very lightweight items - These sheets don't have a strength rating like magnets, so it's difficult to rate how strong they are. This sheet is very lightweight and will only hold the lightest of items. No use for anything lighter than a piece of paper

## Customer Reviews

### ⭐⭐⭐ 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

### ⭐ Only for very lightweight items
*by J***N on 11 November 2024*

These sheets don't have a strength rating like magnets, so it's difficult to rate how strong they are. This sheet is very lightweight and will only hold the lightest of items. No use for anything lighter than a piece of paper

### ⭐ Very weak magnetic properties
*by A***S on 6 January 2025*

The magnetic strength of this is very weak. I'd bought it with the hope of magnetising my Warhammer which has very strong magnets underneath and they will not hold to this. Only really useful for paper etc.
