"Focus On The Good" Cute Aloe Cactus Plant, Waterproof Sticker Positive affirmation sticker measures about 3 x 3 inches. The sticker is 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 that have stickers on them and limiting exposure to direct sunlight.
