FYI. I've had a lot of problems with the removable stickers. I would go back a few days or weeks later and a lot of my flips would be open because the stickers didn't hold. I found just using small pieces of scotch tape worked well and did not show up (e.g. invisible) which was nice to look at. Its cheap and easily found. The stickers were okay, just not very good if they are the removable type.
