This item was purchased previously and has been stored at home for a long time. I purchased two sets and took them out of the bag intending to use them, but ultimately didn't. They are unused. Please check the explanatory images for installation instructions and dimensions. Features: The natural texture of natural wood is a key feature, and it's a convenient double type. Installation: After making pilot holes in the wall with a drill, firmly screw in the screws to secure. Usage: Can be used as hooks for coats, etc. Thank you for looking.
