【Pajamas (Long Sleeve, Long Pants)】“Transforming Sleep into Dreamtime” When sleep is enriched, daily life becomes more vibrant. Based on the concept of “Transforming Sleep into Dreamtime,” we offer a wide range of sleep items, including pajamas designed for "comfortable movement," "comfortable temperature," and "comfortable skin feel," leading you to a joyful tomorrow. We use fine-count, two-ply yarn made from extra-long staple cotton. This twill material features minimal fluff, a smooth texture, and a beautiful luster. The design is accented with piping.
