Envelopes hold together. Glue sticks. Metal brads work and hole well reinforced. As long as you don't need to get in and out of the envelope several times it's a great product. After 4 or 5 folds the metal arms break off. Otherwise good product and a good price.
very cheaply made I am missing over half of the clasps !! Very thin. tear easily I find that the staples products are so cheap that its worth spending the money on real brands.
