In my case, I call the items made of Hoteichiku bamboo with the thickest node diameter of about 10mm or less "ultra-fine." This size is the least common in the bamboo grove where I collect Hoteichiku bamboo. The bamboo has been lightly washed, and the buds have not been removed. The 8th image is a "bonus." I have increased the number of pieces in the set compared to before, and lowered the unit price. Thank you. Size: Thickness: All are about 10mm or less in the thickest node diameter. Length: Generally cut to 33cm.
