No need to drill holes/ Dual-purpose punching!
P.S.: Please pay attention to the installation without drilling. Please watch the video before installation. The wall needs to be flat and solid glass tiles, etc. It cannot be used on uneven and unstable walls such as painted walls, wallpapers, and lime walls. You need to wait after applying glue to the wall. 3- 5 days, the nail-free glue is completely dry before use!
