The height is just barely within the limits, so I think I'll ship it in a vinyl bag via Yu-Packet Post Mini. I don't think I can add reinforcement to the top and bottom, but I will reinforce it as much as possible, perhaps with cardboard or bubble wrap on the sides. If it's nearby, I may drop it in the mailbox while I'm running errands m(_ _)m I'm not very knowledgeable, so please prioritize the images over information like the product name. I've checked for noticeable stains, etc., but I may have overlooked something, so please check the images carefully. If you have any concerns, please ask questions before purchasing m(_ _)m #HeiseiRetro #StorageBox #StorageBoxWithMirror #Pink #mezzopiano #mezzo piano
