These are size 80 undershirts, suitable for children aged 1.5 to 2 years old. I didn't get to use them much when I bought them, so some may be unused. (I don't remember which ones are unused.) The three in the front, purchased from Nishimatsuya, are waffle-knit and cute, while the three in the back, purchased from H&M, are organic cotton and feel nice against the skin. The H&M ones may be slightly larger in size, perhaps because they are made in a foreign country. There are no noticeable stains, but as shown in the second photo, I found a stain-like mark on the blue elbow area. Please understand that these are used items. ⚠︎⚠︎⚠︎Because I have a young child, shipping will only be on Mondays. Thank you for your understanding.⚠︎⚠︎ ※Shipping may be slightly adjusted depending on circumstances. If you are in a hurry, please confirm beforehand.
