Stainless Vacuum Bottle Type M500 Red Clay TW-501-RC For school excursions, cherry blossom viewing, and picnics in the park. New colors added to the popular bottle. A new color has been added to the stainless steel vacuum bottle series, which excels in heat retention and cold insulation by vacuuming the inside to block the effects of outside air. This time, the colors are close to natural colors and are calm, making them easy to use daily and pleasing to women. Also, the wide mouth makes it easy to add ice, and you can enjoy the aroma of your drinks. The bottle is designed with a constriction at the top for easy opening and closing of the lid. We have created a bottle that is useful in urban life, utilizing the know-how we have cultivated in developing camping gear. The stainless steel double-wall construction vacuum-seals the inside to block the effects of outside air, providing excellent heat retention and cold insulation. The Type M series is available in 350ml and a generous 500ml size.
