Thank you for viewing this item. ・This is bamboo material for making a kena. ・It was obtained around 2010 from a professional workshop in La Paz. ・Cut to approximately 40cm in length, with an inner diameter of 17-21mm, suitable for G key kenas. *Please adhere to the NCNR policy (No Claims, No Returns). *This is priced as such due to imperfections such as filled cracks and blemishes, but some pieces are quite heavy. This is a chance to try making a kena with local bamboo.
