This pack includes six adhesive stickers designed for flat hooks measuring 6 1/2 inches. These adhesive strips are suitable for smooth surfaces such as tiles, marble, metal, wood, and tempered glass. They are not recommended for coarse surfaces, painted walls, wallpaper, limed walls, or concrete walls. To install, ensure the surface is clean and dry, then peel off the backing and press the sticker firmly onto the surface. Once applied, place your rack or hook onto the adhesive. For removal, heat the adhesive with a hairdryer to soften it before detaching. These adhesive strips are intended for one-time use and should be applied on flat, smooth, and dry surfaces for optimal adhesion.

The package provides six adhesive stickers suitable for mounting shower caddies or shelves, offering a convenient and damage-free solution for organizing your space. muticolor Nano+Polycarbonate Suitable for tiles, marble, metal, and wood Not for coarse, painted, wallpapered, limed, or concrete walls Needs dry, clean, flat surfaces for adhesion
