Two short-sleeved undershirts for Pooh Although the size selection didn't have anything below 60cm, these are size 50 for newborns. Since they were only used for a short period when the baby was a newborn, they are relatively clean, but please understand that they are used items. I used Arau Baby detergent. I recommend washing them once with your own detergent before use. Available for individual sale 1 piece: 500 yen
