These hand-drawn die-cut stickers are made of durable vinyl. The vinyl protects them from water, scratches, & sunlight. This makes them a perfect addition to any water bottle, journal, laptop, or more! Note: These stickers are waterproof, but may not be dishwasher safe on all surfaces. For best results & longevity, hand washing is highly recommended. Check out the other STEM sticker packs on my profile!
