Yes. They are authentic USPS-issued postage. All of our postage undergoes a series of tests for authenticity and is 100% money-back guaranteed to our customers.

Unfortunately, hundreds and thousands of small businesses and companies are closed every day. They have to get rid of their office supplies such as desks and stamps. We purchase these unused stamps with clearance prices from such companies and our team examines them carefully to ensure items are unused, unfolded, unbent, and authentic. In the end, we sell them on our website at a lower market price.
