These are Heattech undershirts (crew neck) purchased last year and the year before. I'm selling them because my child has outgrown them. Although I'm just a casual observer, I bought a lot of them and wore them frequently, so each one isn't too worn and I think they're still in good enough condition to wear. How about them for growing children or for those who play sports, as spares? Please note that the tag on one of them has been cut off, as shown in photo 9. Also, please understand that these are used items, and I would appreciate it if you could purchase them with that in mind. #UNIQLO #Heattech #CrewNeckT #SizeM
