Used item from my home. This is a hook that you can attach by夹ing it onto板-shaped parts like doors, without using nails or screws. Made of rust-resistant 18-8 stainless steel. The width of the upper and lower hooks differs; the narrower side fits doors less than 22mm, and the wider side fits doors between 22mm and 27mm. You can utilize any space as storage with a little ingenuity (borrowed from the official website's product description). Reference price: 290 yen each (tax included) For those who can accept shipping via Mercari Mail / Yu-Packet Post Mini without using cushioning materials like bubble wrap, and only using a waterproof vinyl bag (like a Ziploc bag). Anonymous shipping will be used. The ruler is not included with the product. Please understand that this is a used item from my home and that there may be some aging. This item is offered as-is. I have tried to show any damage in the images, but there may be oversights. Please feel free to ask for additional images or any questions, and I will do my best to respond. Please review the images and purchase only if you are satisfied. I am currently organizing my collection and listing various items. Thank you for your consideration. Thank you for looking.
