Shipping will be via Mercari delivery (anonymous shipping), but I will ship using the cheapest method after packaging. I may change between Rakuraku Mercari and Yu-Yu Mercari delivery at the time of shipping. I will use simple packaging and recycled packing materials. Shipping may be by sea (land and sea transport), and it often takes a long time to arrive. Thank you for your understanding.
