The Travel mug is a double-layer vacuum insulation cup, which responds to the trend of replacing disposable paper cups and plastic cups with one’s own cups. Through a single touch, the mug is opened with great ease. It boasts a spill-proof and leak-proof structure design, and it’s easy to disassemble and clean. Due to its vacuum state, it can keep the water either warm or cold for a longer time. The curved body makes it easy to hold and carry around. It fits into most car cup holders. Designed for single-handed use, it features a 360-degree drinking range, and a push-button dispenser makes the operation easy and convenient. Waters can either be kept warm for 6 hours or cold for 12 hours.
