Thank you for viewing. This is an Asics short-sleeved crew neck undershirt, size M. It's made of a smooth material. Please note that the color may appear different from the actual product due to amateur photography. The area covered by my finger has a name written on it, so I will cover it up before sending. I apologize if I missed anything. I am also selling the same items, two short-sleeved and two long-sleeved. If you purchase multiple items, I will create a dedicated listing and offer a discount. Please refrain from purchasing if you are overly sensitive. Please understand that this item is stored by an amateur and is USED before purchasing. - Brand: asics - Size: M - Color: Blue
