Your review: Bought these to label shelves in a small warehouse. I had two problems with them when they arrived. One, they were rolled up so didn't want to lay flat. Two, the magnet isn't very strong. So these two issues made it so that these labels wouldn't stay on the shelves right out of the package. I put them under a book for a couple of days to flatten them out and that seemed to help. Very easy to write on & erase.
