This is an anti-pilling knit purchased from Global Work. I think it's perfect for office casual wear in the coming season. I wore it last season and have been storing it in my closet. It shows some signs of wear, but I think it's still wearable. Please feel free to inquire about bulk purchases, etc. The following is quoted from the official website: 【Material/Features】 This item uses a high-gauge jersey knit fabric made by knitting fine viscose nylon yarn together with stretchy nylon yarn. It has a moderate firmness and drape, and an elegant luster. It's a cool material with a smooth feel. In addition, it is resistant to pilling and is machine washable, making it an easy-care material. 【Design】 This is a crew neck knit with a simple design that is easy to mix and match. It has a moderate amount of room, but it's also designed to be worn comfortably as an inner layer under a jacket. We paid close attention to the size to make it easy to mix and match. --- 【Recommended Styling】 In early autumn, you can wear it as a single layer over a T-shirt, or layer a shirt underneath and then wear a jacket over it. It's an item that can be styled in various ways depending on the temperature and occasion. Even when paired with casual bottoms like denim, it won't look sloppy and can be worn with a mature impression.
