Individual postcards - it's easy to make them yourself! HERMA postcard labels turn photos and pictures into very personal postcards for mailing: simply peel them off the backing paper, stick the postcard label on the back, and that' s it. The labels measure 95 x 145 mm, making them ideal for photo formats 10 x 15 cm or larger. The photo-friendly material is particularly opaque and robust, ideal for covering shipping labels, for example. The paper is chlorine-free bleached and the adhesive is solvent-free.
