Thank you for viewing. The main body has a double-layered stainless steel construction, allowing for both heat retention and cold insulation. After all, this is a chai server used by people selling chai on the streets of India. Cold chai is unsellable. There is an air layer between the double cylinders, providing insulation. It's not vacuum insulated, so it's not quite as effective as that. However, it's more effective than single-layer stainless steel or resin products! The lid also has a double-layer structure. Furthermore, the sales shop, Naturum, had replaced the original tap with a high-precision domestic tap before selling it. It has a strong presence, so it will instantly make your site stylish! Also, it's already discontinued, so it's less likely to be seen with others, and it's becoming difficult to obtain. The Highlander sticker has been removed, and a Chums sticker is affixed.
