"Jiu-Jitsu - The Art of Folding Clothes While People Are Still in Them" Waterproof Sticker This martial arts die cut sticker measures about 3 inches tall. All our stickers are handmade with a high-quality waterproof sticker material, and an extra UV protectant has been added to help them last even longer outside. However, fading should be expected with long-term sun exposure. Stickers have permanent adhesive and will not be easily removable once applied. To ensure the longest life possible, we recommend handwashing items with stickers and limiting exposure to direct sunlight.
