I ended up buying too many short-sleeved undershirts and didn't end up using them for my child. They are unopened, but have been stored at home, so please refrain from purchasing if you are at all concerned. They can be used in various ways, not only in spring and autumn, but also in winter, worn under quilted combination undershirts! To keep shipping costs down, they will be sent in an envelope as is. I can change to Mercari delivery (Nekopos) for an additional 50 yen, so please let me know if you would like this. If you have no questions, you can buy immediately! 100% cotton newborn undershirts, a convenient set of 2, machine washable. - Brand: hohobaby - Quantity: Set of 2 - Size: 50-60cm - Material: 100% cotton - Target age: Newborn to 3 months - Features: Machine washable Type...Innerwear Sleeve length...Short sleeve Other...Front opening
