This is an "Inner Core Fire Staff" that I purchased new over 10 years ago from the juggling shop "Naranja" for 27,300 yen. It is no longer sold at Naranja. Fire has only been lit on one end once. It has a disassembled structure, making it convenient to carry. There are no problems with attaching and detaching. The length after assembly (when in use) is 99cm. I will package it with vinyl for rain protection and cardboard, and ship it via Mercari delivery. Assembly Instructions: Hold the center in your left hand and the fire-lit part in your right hand, with the fire-lit part on top. Without moving the left side, rotate the right side clockwise to secure it. You'll understand it immediately. It seems like it's in the middle of a negotiation, but anyone is welcome to purchase it.
