I obtained this about a year ago. It's an old wooden thread spool. There's a "three" (三) branding inside a circle (○) on both sides. Dark beige thread is wound on it, but the length of each is unconfirmed. The weights are approximately 65g, 70g, and 90g respectively. The thread has some frayed areas. Overall size: Length 95mm, diameter 55mm Size of the core for winding the thread: Length 75mm, diameter 30mm The hole in the center is 6mm in diameter. There are scratches, etc. Please check the photos. Popular words... Antique, old tools
