I chose 24 cm because the person who wore them was a 24 cm size! I measured them just in case, so please use it as a reference m(_ _)m I will pack them as they are, without cleaning. Simple packaging. For Takkyubin (home delivery service), I will use cardboard boxes, paper bags, or宅配ビニール袋 (delivery vinyl bags). I may use recycled materials. If it's necessary to fill any gaps, I will use newspaper.
