Purchased new nearly 10 years ago and stored in a dark place after use. The outer circumference has scratches. Adhesive tape is used to secure it as shown in the image to prevent the tape from unraveling. (I may re-secure it with cellophane tape or masking tape when shipping.) It has likely been used more than half. The remaining length is unknown. (Based on information such as the wrapped thickness of about 5mm, the cylinder diameter of about 8.5cm, and the outer circumference of about 30cm, AI calculated that the length might be 30-35m. The length is not guaranteed. This is just for reference.) When shipping, I plan to wrap it in plastic and place it in a cardboard box without using cushioning material. I may use cushioning material to fill the gaps. If you have any concerns about packaging, shipping methods, or anything else, please contact me before purchasing.
