I like these better for mailing then the ones with the silver thingy. Also because they are white so much better to decorate the outside for my grandkids.
After taking the paper tabs off the closing flap most of the envelopes did not stay glued completely. I needed to use Scoth tape to seal the envelopes completely. Time consuming and not the kind of presentation I wanted to make. Dan
Great product & price. However the adhesive needs to stick until ready to be opened by the recipient. I had to add extra adhesive within 24-hrs and I hadn’t even gone to the post office to mail.
