Quality Material: The suction cup hooks are designed for drop ceilings and are resistant to deformation and rust. They offer strong load-bearing capacity and excellent adhesion. Strong Adhesion: These hooks create suction by removing air between the hook and the surface, generating pressure differential. For best results, use on clean, smooth, non-porous surfaces such as glass, metal, ceramic tile, wood, or marble. Package Includes: 200 damage-free hanging hooks and 200 metal hooks. Hook diameter: 3 cm (1.2 inches); hook length: 2.1 cm (0.83 inches). Sufficient quantity for various hanging needs. Easy to Use: Remove the protective film from the back of the hook, press firmly onto a clean, smooth surface, and squeeze out trapped air. Then attach the metal hook and hang your decor. Wide Application: Reusable adhesive hooks ideal for events and everyday use — including birthdays, parties, weddings, Christmas, Valentine’s Day, home, café, bedroom, balcony, etc. Suitable for banners, plants, window decorations, wind chimes, posters, and string lights.
