Vintage from the 20s-30s! This is an old shoe button hook (shoe hook/boot hook/button hook) that was used in America back then. The material is hard iron/iron, and the size is 7.7cm in total length, with a width of about 2.4cm for the circular part. Condition: USED, used in America, with the texture of an old item, peeling plating, scratches and scuffs, rust and discoloration, a vintage taste, atmosphere, and aura! It has a great atmosphere and is COOL, so we've included a ball chain as a bonus so you can use it as a key holder, perfect for accenting your key ring! Originally, it was a tool to assist with attaching buttons on boots, etc., by inserting the hook into the buttonhole and hooking it onto the button to pull it out, making it easier than using your fingers. However, since it's made of hard iron, it could also be used as a non-contact tool for elevators, ATMs, door openers, etc., without touching buttons! For those who understand old items and appreciate the romance, thank you! Shipping is by regular mail, free of charge!
