coffee mug 500ml-Vacuum Insulated Tumbler 500ml, coffee mug 500ml-Vacuum Insulated Tumbler 500ml A Vacuum Insulated Tumbler (500ml) is a type of travel mug or beverage container designed to keep liquids hot or cold for extended periods. It uses double-wall insulation technology with a vacuum layer between the two walls to minimize heat transfer. This allows the tumbler to maintain the temperature of the beverage inside, whether it's hot coffee, tea, or cold drinks like iced water or smoothies. Here are some key features you can typically find in a 500ml vacuum insulated tumbler: Key Features: Temperature Retention: Hot drinks: Keeps beverages hot for hours, usually up to 6-12 hours depending on the design. Cold drinks: Can maintain cold temperatures for up to 12-24 hours, making it ideal for icy beverages. Material: Most are made from 18/8 stainless steel, which is durable, resistant to rust, and BPA-free. The outer layer is often powder-coated or stainless steel for a sleek look and added durability. Leak-Proof Lids: Many models come with a secure, spill-proof lid, perfect for on-the-go use. Some lids feature a one-handed opening or straw hole for easy drinking. Compact Size (500ml): This volume is perfect for a personal-sized drink—enough for coffee, tea, or water but not too large to be bulky. It's ideal for commuting, gym use, or office settings. Ergonomic Design: Most tumblers are designed to fit comfortably in your hand and in car cup holders. The size is often optimized for easy carrying and portability.
