Using these envelopes is more sanitary because they are self-adhesive. It saves me lots of time and looks professional. I don't worry about moisture causing them to open.
This is a high quality product. It's sticky surface prevents licking unsavory strips for securing the envelope shut. It is a durable professional and simple product.
I can't believe this product! It is great for letters...no more taping and pasting together an extra peice of paper to transport my correspondance in...these ones are already made! Just fold your letter into thirds and - Presto! - slip it in this little product and remove the magic strip and it becomes sticky enough to seal itself closed! I know...CRAZY! Not only that but these come in boxes of 100! What!?! A hundred that's right 100! In one box!?! Once I saw how cool these "envelope" things were I went right back and bought another box! I thought I better stock up before everyone finds out and then all the "envelopes" are gone...
