We dont seal them so I cant tell you how they stay.These cute pink envelopes fit our gift cards perfectly - exactly what we needed. Good quality at a good price.Nice little mini envelope. Only negative is they are a very pepto bismol pink so much brighter than the picture online.These were exactly as described and are great gift card sized envelopes.Bought these to put gift cards in to send out to clients. Can fit a few cards if you wanted to!I was searching for self-adhesive envelopes to use for gift cards we give to our group of 120 employees. Self-adhesive being key so that I do not have to moisten 120 envelopes. When I saw these, I thought it was perfect. I checked the dimensions and it was good enough for gift cards albeit, slightly oversized. When they arrived, to my displeasure, I discovered they are gummed. Hello seller, GUMMED IS NOT THE SAME AS SELF-ADHESIVE? Weight of paper is great as is color. Using key words to search should bring up accurate product description; not what the seller wants you to think they are selling. Will not buy from this seller again.Good quality and consistentMuy bonitos y practicos
