I bought several packages of these for our preschool program mostly because of the great price. When we first tried to take the caps off we found them difficult to remove and some children needed help. Otherwise they worked well and were a good bargain for the money.
The adhesive appeared to work but after a couple of days the paper seperated from the page. I ended up using double sided scotch tape. I would not buy again. Poor quality. Glue that does not stick is useless.
