Sleep-time: ● Mysterious Neck and Shoulder Pajamas That Don't Get Your Body Cold ● Mysterious Socks That Don't Get Your Feet Cold These items provide thorough insulation for the neck, shoulders, and feet, which are prone to getting cold, while the areas that tend to sweat have moisture-wicking and breathable properties. They use a material with a marshmallow-like feel. Unopened, they will be shipped in a Takkyubin Compact box. Individual sales are not possible. The packaging may have wrinkles due to home storage.
