I am selling this item because I no longer have use for it. Length: Approximately 7 cm Thank you for viewing. No comments needed, immediate purchase is welcome. No price reductions, please. Bundling is a great deal! Buy 2 items, get a 300 yen discount! * Due to the strong spring of the safety pin, please be very careful not to injure your fingers when opening and closing the lock. The pin is thick, so it will make holes in fabrics like cotton or linen. When fastening to clothing, loosely knitted materials like yarn are suitable. Delivery will be via Yu-Packet Post Mini. Material: Alloy Simple packaging. I also have many other items for sale, including brass carabiners, wallet chains, vintage stainless steel, and brass keychains. Due to the nature of the product, there may be scratches and stains. The product may have rice husks attached from the manufacturing process. Please understand this. Please check the images before purchasing and we appreciate your understanding.
