Brass "hibuki-take" (fire-blowing bamboo). The material is all brass. The bamboo joints were carved out of brass. By the way, it is not a split type. It is a complete single tube. (Only the cap at the tip is screw-type) There is a slight gap in the joint on the hand side (mouthpiece side) so that paracord etc. can be passed through. You can use the paracord as a hand strap or hang it on a hanger. It also prevents rolling. (Please be careful not to mistake the direction of the mouthpiece and the tip. The wider hole is the mouthpiece) *Comes in a special paulownia wood box. 【Details】 Material: Brass Total length: Approximately 46cm Maximum diameter: 24mm Please refrain from purchasing if you are nervous about home storage. Thank you for viewing.
