Thank you for viewing! (*^^*) This is a set of two long-sleeved, fluffy, warm knit-quilted underwear from Birthday. Although it looks black, it's actually navy, as it's described as "dark navy." Plain and striped. The collar and cuffs use ribbing that doesn't stretch easily. Stretch rib specifications. New, unopened. Will be shipped via Nekopos or Yu-packet Post. Even if it's an unused item, it's a product that was on display in a store and has been stored at home by an individual, so please purchase it if you understand this.
