This is a set of 4 newborn baby undershirts (1 short-sleeved undershirt, 2 long-sleeved undershirts, and 1 combined undershirt). Size: 50-60cm These were only worn a few times, so I personally think they are in good condition, but they are used items that have been worn several times. Thank you for your understanding. Please refrain from price negotiations. I am also selling other baby items such as undershirts.
