The Magne vacuum flask is an innovation that keeps warmth and attention. The Waterline flask is not just a container for drinks, but a technological accessory that combines advanced solutions and impeccable design. Made of food-grade stainless steel AISI 304, it is safe, durable, and resistant to external influences. With a volume of 500 ml, it is ideal for daily use - in the office, on the road, or on a walk. Thanks to the well-thought-out thermal insulation system, the flask keeps warmth for up to 24+ hours, and hot drinks for over 15 hours. This became possible not only due to the double vacuum walls of the body with additional copper insulation, but also thanks to the unique design: the inner screw-in liner also has a vacuum layer, which minimizes heat loss through the neck. The main feature is the magnetic lid-cup with double vacuum walls. It instantly comes off and returns to its place (in less than a second!), providing comfort and a wow effect. Powerful neodymium magnets securely fix the lid - even when turned upside down and shaken actively, it will not come off. The flask comes in a signature Waterline craft tube - a stylish, eco-friendly, and premium packaging that emphasizes the gift status and is perfect for corporate programs, loyalty, promo campaigns, and retail sales. Such a flask is not just given - it is noticed, used with pleasure, and recommended to others. • Magnetic lid-cup with vacuum insulation - fixed in a second, does not fall even when shaken, and does not burn hands. • Well-thought-out thermal insulation system: vacuum in the body, vacuum in the inner screw-in liner, and vacuum in the lid - maximum temperature retention (hot 15 hours, warm 24 hours). • Made of food-grade stainless steel AISI 304 - safety, durability, and corrosion resistance. • Exclusive design and engineering work - a flask that truly captures attention and stands out. • Comes in a premium Waterline craft tube - the perfect packaging for corporate gifts and retail sales.
