No tools are required, just like a thumbtack. This hook is for use on plasterboard walls and leaves no visible marks when removed. We used "Rakupin," which is a system of pins that are crossed and pushed into the wall to secure the wall.
・This product is for use with plasterboards of 9.5 mm or more. Do not use on ceilings. - Do not apply load to the hook in any direction other than vertically. - Do not hang the hook in a way that places the load only on the tip of the hook. ・Do not hang valuables or fragile items. ・Please carefully read the instructions for use and precautions on the package before using.
