These thin, breathable undergarments feel great against the skin, making them perfect for children. I'm selling these because my child has outgrown them. They didn't get much wear because of the rapid growth spurt from late elementary to middle school. Therefore, they are in good condition with no significant wear and tear, and I believe they can still be used for a while. This is a set of three 160cm undershirts made of a polyester and cotton blend. - Set includes: 3 shirts - Size: 160cm - Material: 70% polyester, 30% cotton - Country of manufacture: Philippines Thank you for looking.
