The camping mug is made of durable and hygienic 18/8 stainless steel, naturally free of BPA. It has a capacity of 230 ml. It is perfect for camping trips and outings in the city. Thanks to the vacuum insulation between the two walls, the mug keeps the hot drink temperature for 1 hour, cold for 2 hours, and even up to 10 hours with added ice cubes. The vacuum insulation, in addition to thermal properties maintaining the drink temperature, prevents the outer part of the mug from getting wet from the cold drink inside or burning hands from the hot drink. The transparent lid made of tritan has a hole that allows drinking without removing the lid from the mug. The mug is not leak-proof when the lid is on. It makes a perfect set for a Stanley travel drip coffee maker. It is dishwasher safe. Washing dishwasher-safe products may cause faster deterioration of their visual properties compared to hand washing over time. If it is important for you to preserve the appearance of your product longer, the manufacturer recommends hand washing with a gentle sponge.
