This peculiar yet practical device is an astonishing contraption. It looks to be a specially-cut cardstock that has been folded and glued to form a receptacle that one may put other pieces of paper in. What is even more astonishing is the clasp and glue adhesive that would allow you to seal it temporarily or permanently. I could envision a multitude and dizzying array of practical applications for this "catalog envelope". I could use it as an envelope or to keep my catalog protected or use it as an envelope. Its applications are endless. Thank you Staples for another 5 Star product. I rank this innovation up there with the eradication of polio and space travel.
I was very pleased with these envelopes. The clasp was good and solid and remained attached to the envelope when folded into the closing position. The gummed portion also remained sealed when moistened and closed. I will keep using these 10 x 13 clasp envelopes in the future.
