This is a stainless steel "trash can lid (swing type)" designed to be embedded in kitchen counters, etc. Stainless Steel Material: Made of durable and clean-looking stainless steel, it blends well with kitchens and washrooms. 360-degree Rotating Swing: The lid rotates, allowing you to easily dispose of trash from any angle. Space-Saving: As it's designed to be embedded in the countertop, it doesn't take up space for a trash can, and you can drop the trash directly below. It can also be used as a lid for regular trash cans. It can be placed on top of trash cans from 100-yen shops, etc. It's also good for hiding the trash can. Size: Approximately 25.5cm Inside: Approximately 19.5cm Width of the groove on the back: Approximately 2.5cm. If using it as a trash can lid, it will fit within this width. Although it is unused, it is a used item, so please refrain from purchasing if you are sensitive to this. Immediate purchase is fine. Thank you. ^_^
