We are wall decal designer , and our decals are 5-year indoor/outdoor vinyl with permanent adhesive so they won't peel. They are fade-resistant and can be removed gently (not reusable) without marring the surface. Please clean area before applying. Instructions for application will be sent with order. Recommended for flat surfaces such as finished wood, glass, metal, plastic and drywall. Not recommended for areas with rough, flaky or powdery surfaces.
