This is a drafting weight (1 piece) from Uchida Yoko. The surface of the weight is wrapped in soft leather and sewn, so it won't rust or stain drawings. Model number: 818-0075 *Discontinued Round, lead-based Diameter 75mm, thickness 20mm Weight approximately 940g This is an unused item that was stored long-term in the warehouse of a shop run by my grandparents. Therefore, there is some age-related soiling on the leather surface, and the box also has some discoloration and stains (photos 5 and 6). Please understand this before purchasing. ☆ There is one more in stock, so if you would like to purchase multiple, please comment (2 pieces including shipping for 7,200 yen). ☆ We also have other Uchida Yoko products for sale (planned). #cottonrose_uchida ************************************* ☆ We also sell Showa-retro stationery and stationery novelties. #cottonrose_retro If the items can be shipped together, we will offer a small discount, so please comment before completing your purchase (^-^) ※ We are also selling on other flea market apps, so we will prioritize the first person to purchase. Also, we may suddenly remove the listing. Thank you for your understanding. #UchidaYoko #DraftingWeight #Weight #Round #Lead #Leather #uchida #Drafting
