Unopened. 【Soft and Zero Restriction】The Luckmast belly band has excellent elasticity and doesn't constrict the abdomen, making it especially recommended for pregnant women. It warmly wraps the lower back and abdomen, which are prone to feeling cold, and also provides heat retention. It fits perfectly even for mothers in the late stages of pregnancy with a waist circumference of 1 meter, and can be worn comfortably with its soft feel. It is also popular as maternity underwear due to its thin, soft material and excellent elasticity, and can be worn by men and women of all ages. 【Maintain Health】Since ancient times, warming the abdomen has been said to warm the "Tanden" (a point in the lower abdomen), leading to overall health and improved immunity. This ancient Japanese health wisdom has been revived in modern life with the latest high-performance materials. This product is not just about warming; it is a belly band that pursues a skin-friendly feel and functionality that can be used in all aspects of daily life. 【Comfortable to Wear 365 Days a Year】It's thin yet warm, gently moisturizing the abdomen and lower back. It's perfect for winter cold protection, as well as for preventing chills while sleeping and for summer air conditioning. It's thin, so it doesn't show under clothes and is less likely to make you look bulky. It also has excellent moisture absorption, quickly absorbing sweat and releasing moisture, so you can stay comfortably dry all year round, even in summer. 【Warm Your Abdomen】In spring, the temperature difference between day and night, and in summer, the temperature difference between outdoors and air-conditioned places, can disrupt the balance of the autonomic nervous system, often causing the body to cool down without you realizing it. Warming the abdomen is the most important thing to improve circulation throughout the body. Cold is the enemy of health, so use a belly band regularly to warm your body. 【Easy to Wash】Use a neutral detergent and gently scrub by hand. If using a washing machine, it is recommended to put it in a net.
