1 Oz First-class Forever Stamps, Thank You, 20/pack

Forever stamps are always equal in value to the USPS 1 oz First Class mail price. Stamps are self-stick (peel and stick) for easy mailing. USPS Forever Stamps are always valid for 1 oz First Class Mail, even when the rates go up, so stock up now before the next rate increase. Each stamp has a face value equal to the current Forever Stamp rate, so you can use multiple stamps or additional postage to cover your total shipping cost.
