The Stanley Legendary Classic vacuum insulated vacuum flask maintains temperature for up to 24 hours. The design of the thermos has enhanced strength and impact resistance by reducing the vacuum between the steel walls. It has a leak-proof lid, so you only need to unscrew and tilt the thermos a little to fill the cup. This solution protects the drink from unnecessary cooling and accidental loss of the cork. The thermos is 100% sealed. A folding handle with a comfortable finish ensures a secure grip. The vacuum insulation used between 2 steel walls allows you to keep the temperature of the drink for 24 hours and the ice for up to 5 days. The wide inlet makes emptying easier and allows for thorough cleaning of the interior. Made of extremely durable 18/8 stainless steel. Can be washed in the dishwasher.
