I purchased this from a Korean children's clothing website, but I have never used it. It had a slight odor when I bought it, so I washed it with water once (with fabric softener). It will be shipped via Click Post. No price reduction. Although it's unused, the collar had a slight crease when I purchased it. It's a long-sleeved T-shirt. The fabric is a bit thin for a sweatshirt, so I think it's good for spring and autumn. The collar is not removable. Since it's made overseas, the sewing may be imperfect or there may be some fraying. Please understand this beforehand. There was only an outer size tag, and no other tags were originally attached. The fabric is unknown. FHW
