Children's Clothing Kids' Pants Rib Knit Pants Korean Children's Clothing Korea Long Pants Black 100% Cotton 120cm Unused. Ships via Yu-Packet Post. No price reduction. Due to being made overseas, there may be some areas with rough stitching. Please understand this before purchasing. Also, there was a very long tag attached, and I cut it off because I thought it would be in the way. I don't think it will be a problem, but please check the photos. The fabric is smooth, but it's 100% cotton. It has elasticity.
