This is a set of Miki House short-sleeved undershirts and combination undershirts. - Size: 50cm - Material: Cotton Thank you for viewing. The size is listed as 60cm because there is no 50cm option, but as shown in the photos, it is 50cm. The short-sleeved undershirts have been used a few times, so they are in relatively clean condition. The combination undershirts show signs of use, but there are no noticeable stains. Please refrain from purchasing if you are concerned, as this is a personal inspection and the items are stored at home.
