JAM PAPER 9 x 12 Open End Catalog Envelopes with Clasp Closure – Smooth Black – 25/Pack

Purchased many times as these are used regularly throughout the year.Clasps are the only downside although unavoidable given the material. A short string tie may be better for securing closed as the pins will snap off after several times opening/closing them. The result is sharp edges once the two folds break off.That being said, will continue to purchase as needed.
