Instant purchase is welcome without any comments! I will pack it with cushioning material and ship it via anonymous Yu-Packet Post Mini. ☆ I have a cat. 【Please follow Mercari's rules.】 ☆ I do not accept exclusive listings. ☆ I do not accept holds. ☆ I will prioritize those who purchase immediately.
