Forever Stamps are always equal in value to the first-class mail one-ounce rate.
 Send greetings to friends and family with a new forever stamp. Not only great for postcards, letters, mailing envelopes or collecting, but for collectibles, birthdays, teachers, occasions, weddings, parties, showers, celebrations and more.

How to use

Forever stamps are stamps that will never expire. You can still use them even when the price of mailing a letter goes up.
There is no face value or amount on the stamps. With self-adhesive, easy to stick to. When the Forever Stamp is affixed, you could send mail no more than 1 ounce.
