Thank you for viewing! I received this as a gift, but I already have one, so I'm selling this brand new item. The material is special and feels amazing to the touch♡ Description: Temperature-regulating SMOOTHIE This item uses 'Smoothie' material, known for its melt-in-your-mouth smoothness, and incorporates temperature-regulating yarn. This functional material adjusts warmth according to the temperature, allowing you to stay comfortable even during seasons with fluctuating temperatures. Perfect for the coming season! Let's boost our mood at home by wearing cute loungewear♩
