I am a teacher. My class uses glue all the time. This was the worst glue ever. It hardly stuck to another piece of paper. Will never buy this product again.
This is a great product. I use them to repair book dust jackets...they are fast-acting clean no fuss no muss. Hard to get the caps off but I found solution...place unit cap on edge of table and press lightly on tube...pops right off. Struggled a while with that one.
