We used tightly twisted cotton yarn for a cool and comfortable feel. The cotton was grown in the nature of Africa. Please refer to the photos for the specifications. It was sold for 2990 yen (tax included) on the official website. I received it as a birthday present, but the size doesn't fit, so I've kept it folded in a drawer without wearing it even once. The tag is not attached. It is a new, unused item, but it has been in someone's possession, so please refrain from purchasing if you are sensitive to this. Immediate purchase is welcome. We will ship via anonymous delivery. Please refrain from comments asking for a price reduction.
