Using these stickers is super easy! Just peel them off the roll and stick them on whatever you like, such as envelopes, tissue, bags, or boxes. They'll add a really nice, personalized touch. When using, make sure the surface is clean and dry for the best sticking result. As for maintenance, keep them in a cool, dry place. Since the ink is water - resistant, they can withstand a little moisture, but try not to soak them in water for a long time. Enjoy decorating with these lovely stickers!
