These glue sticks are convenient and not messy. The retraction features a plus in storing it away. One draw back the small percentage that is left in the well area.
I buy tons if these when they are on sale for my classroom. They work great on the many projects I do in the classroom and are great for my kids to do when they want to help with the picture documentation posters we make so our families can see what us going on in the classroom. They last as long as any "name brand " glue sticks!
I found that these washable glue sticks do not hold as well as non-washable glue sticks. As a teacher I need for items to stay mounted to construction paper--both copy paper and construction paper. I had to reapply the glue several times. I had problems with the paper coming up and not lying flat. Several items come completely off the mounting.
