Recently, we've started selling on another site, so although extremely rare, there's a possibility of simultaneous purchases. In that case, we will prioritize the first purchase, and the second purchase will be canceled. Thank you for your understanding. This material was drilled a while ago and then forgotten, as it was for made-to-order items. However, since made-to-order production has recently concluded, I've made it. The image is of the mizuhiki (decorative cord) before the glass coating treatment, but the finished product will look almost the same. The glass coating itself doesn't impede the wood's natural breathing, so it will age over time. It is not completely waterproof, so leaving it in contact with dark-colored liquids like coffee or tea for an extended period may cause staining. The metal fittings in the image are for photography purposes, so they may not be fully inserted or may have scratches. However, we will ship the product with new metal fittings. Please use them as an assembly reference. The size is approximately 140mm in total length, with a maximum shaft diameter of approximately 12mm and a clip side of approximately 10mm. The weight is approximately 19g. It is a single-action, fixed-type pen without a guide pipe.
