This is a black cotton-silk ribbed V-neck cardigan from MUJI, purchased a few years ago, size M. It's easy to match with anything and can be worn in many seasons. I'm selling it because my style has changed and it's been sitting unworn at home. It's new and unused. The size is: width 46cm, length 57cm. The material is 80% cotton, 20% silk. Although it's new and unused, please understand that it has been stored at home, so please consider it as a used item before purchasing.
