The mug is lighter than steel.  Lid with a flip-down valve for drinking, which opens 180° and does not interfere with use.Mugs are not designed to maintain the temperature of drinks for a long time, but still, thanks to the double-walled design, it keeps the heat (or coolness) of the drink for about 3 hours.Recommendations for use:• Before first use, thoroughly wash the product with hot water and detergent, rinse well and wipe dry to avoid water stains on the surface.• The product is not 100% sealed. It is not recommended to put the product in bags or backpacks. Carry the mug in an upright position.• We recommend washing the thermocup manually. Aggressive detergents used in dishwashers can damage the paintwork.• Caution! The drinks you are going to enjoy can be very hot.After filling the thermocup with boiling water, let the liquid cool for 1-3 minutes, do not close the lid immediately or leave the valve open for a short time. This will avoid increased pressure, pushing the lid out of the thermocup and deformation of plastic elements.Actual volume: 630 ml Useful volume: 500 ml Dimensions without packaging: 95x90x189 mm Dimensions with packaging: 96x96x195 mm Weight without packaging: 221 g
