Thank you for viewing my work. This is a belt that can be wrapped around the waist, created for convenience when you want to warm or cool a part of your body. This time, I've designed it with vertical pockets to prevent items like phones, keys, and drinks from falling out, making it useful as a pocket. Magic tape is attached to the sides of the elastic. Please put it in the small bag and wrap it around your body. The photos show it worn over clothing, but you can also wear it over underwear if needed. There are no metal parts, so it won't hurt even if it touches your skin or if you lie down. I'm including a simple cooler bag made of aluminum sheet as a bonus. It prevents things from getting wet and keeps things cold for longer. * Use with a cold pack for: * When you have a fever * Heatstroke prevention in hot weather * Heat対策 for strollers * Bruises, muscle pain, and burns * Itching * Use with a heat pack for: * Lower back pain or old injuries * Warm-up activities * Cold weather対策 * Use as a pocket for keys and phones: * Waiting for a phone call, when you're concerned about the time * Quick gardening * Taking out the trash * As a pocket for a trip to the convenience store * For valuables when you can't carry a bag or want to hide them: * During sleep on late-night buses or group trips * Staff at events like bazaars and sports days * Heatstroke対策 * Freeze a pouch of juice slightly for hydration and a cooling effect Depending on the size you wrap around your body, you can wrap and secure it around various places like your thighs, calves, knees, arms, shoulders, waist, head, and neck, as shown in the photos. (The elastic belt is removable, so you can also use it with your pants belt or a string.) Please check the temperature, as it can get hot or cold, and avoid direct contact with the skin. Black elastic Width: 2.5-3 cm Soft magic tape: 20 cm Hard magic tape: 10 cm When the elastic is not stretched, it can be fastened to about 70-80 cm. If in stock, I can make adjustments to 60-70 cm or offer extension belts. Please check the size you need before considering a purchase.

I created this as something that might be useful for first aid, and I use it all year round, but please refrain from purchasing if you have any concerns. Thank you.
