This sticker is waterproof and finished with a UV coating that will keep it shiny and vibrant for up to 4 years! The holographic material captures light beautifully, creating pools of color that shift on the surface as it moves around. The design is part of my illustration series inspired by witch familiars— a concept from the medieval era that witches were aided in their magical work by shapeshifting creatures that took the form of common animals. These stickers allow you to bring your chosen familiars along with you anywhere you go! Dimensions: 3.4 x 2.15"
