This is a set of four short-sleeved undershirts from Miki House Hot Biscuits. The size is 50. They were used during the newborn period for my first child in 2022 and my second child in 2025. There is some wear and tear, but the fabric is durable and still usable. - Color: White - Sleeves: Short sleeves - Size: 50cm If you buy multiple items, I will offer a discount, so please feel free to consult the comment section.
