This is a set of 11 infant undershirts, including short-sleeved and long-sleeved ones. Purchased from Rakuten and Nishimatsuya, they were used for 1-2 months. All sizes are 50-60 cm. Since there are shipping costs and they show signs of use, I'm considering getting rid of them, but if anyone would like to use them even at a low price... Thank you for looking.
