I am selling this item because the size was too large for me. The size is listed as SS, and after searching, I found that it corresponds to 21-21.5 cm, so I've listed it as 21 cm. Although it is new and unused, there may be some dirt or scratches from storage. Shipping will be within 4-7 days, but I may be able to ship it earlier depending on my work schedule. I will not include the box, but will take measures to protect it from rain and use cushioning material for shipping. Instant purchase is available.
