INSTALLATION TIPS: If there are oil drops on the walls of your kitchen, please remove them before installation. The weakness of the self-adhesive hook is that if the ambient temperature is too high or the surface of the object is rough, it may fall off more easily. Therefore, please keep away from the stove and the water heater before installing it. WATERPROOF AND RUSTPROOF, CARBON STEEL MATERIAL: The kitchen towel rack adopts a carbon steel anti-rust material. And its exterior is coated with safety waterproof paint. Of course, the material is safe, non-toxic and BPA free. WARM REMINDER: Please be sure not to overload when using the paper towel holder. Be sure to install it on a smooth object and make sure that there is no dust on the surface of the object before installation. MULTIPLE INSTALLATION OPTIONS: Vertical or horizontal (left or right), paper towel roll holder is ideal for installation under sink storage or on the side of cabinet (on a cabinet door, under cabinet), which is the ideal accessories to replace the countertop holder and perfectly save the counter space.
