Circle Nail Puller Pet Clothes Playing Cards

The 'Maru ni Kuginuki' crest, also known as 'Kuginuki mon,' is an emblem inspired by an old, large carpentry tool used to pull out big nails. It is based on the principle of leverage, consisting of a wedge-shaped washer and a lever. Also referred to as 'Senkin' or 'Manriki,' it is said to have the power to conquer nine castles, making it a symbol of good luck in military contexts. (Compiled by Kousaku Ito in 'Japanese Crests'). Not only was it used by daimyo and their samurai, but it was also commonly used as a design on the happi coats of servants and retainers, though the exact reason remains unclear (written by Raisuke Numata in 'Japanese Crest Studies').
