Using these stickers is easy! Just peel them off the roll and stick them on your desired surface like envelopes, bags, or boxes. They'll add a nice, personalized touch. When using them on cello cellophane bags or cupcake boxes, they'll seal them in a cute way. As for maintenance, keep the roll in a dry place to avoid the adhesive getting damaged. Since the ink is water - resistant, a little bit of moisture won't ruin the design. But don't soak them in water. Also, when peeling the stickers, do it gently to prevent them from tearing.
