Review on 32 Lovely Kawaii Special Design Retro Envelopes & Stationery Writing Letter Paper Set - SCStyle 16 Cute Chinese Style 8.46 X 4.33 Inches & 10.2 X 7.3 Inches by Olusola Reid

These envelopes and writing sheets are gorgeous! The designs are artistic and classy at the same time. Each design comes in its own individual plastic envelope. BUT! there is a major problem with the envelopes. They open on the side.no real problem.but have absolutely no adhesive on the flap! My glue stick doesn't work well on it, and it is a big hassle to try to glue the end shut to mail a letter. Why, when manufacturing such a premium product, leave out a critical feature like adhesive/glue on the envelopes? Maybe it is a mistake? I wonder if all of them have this problem, or just mine?
