Lost ocean Small Padded Envelopes 3x5 - Pack of 20 - Bubble Yellow Kraft Bag Mailers - Mailing Envelopes - small bubble envelopes - Yellow Pouch

When I read the details it said the outside dimensions were 4 x 5.5. It is really only 3.5 x 5.5. And the inside is more like 2.5 x 5. Even though USPS will allow a 3 x 5 mailer, this envelope is so small there is barely enough room for a return address, recipient address and stamps. It is what I ordered, but buyer beware it is very small, you will have to write small....Quality is good, and flap adhesion is good.

The envelopes are perfect for mailing thumb drives. However the Post Office charged $3.50 to mail even though the envelope wasn't heavier than a letter. The postal clerk said the thickness of the thumb drive made it a package instead of a letter.

Durable and perfect size for mailing small jewelry items

Adhesive was only partly across the flap. The only item sent was an SD card. It was returned for postage. Takes 2-first class stamps

Used to mail small Christmas gifts - trying to save money- however the postal worker who processed my packages said that because they were so small, they could easily be lost. She suggested that I go with a slightly larger size the next time. The envelopes arrived on time and worked well except for what I was told at the post office.
