An elegantly hand -cast magnet is integrated into the base of the plastic glasses. To ensure that the glasses stay in place during the journey, they must be combined with a metallic counterpart . The set includes two metal nano-gel pads for this purpose. The force ratio between the magnetic glasses and the metal nano-gel pads is perfectly balanced, so that the glasses are held in place by the pads on the one hand, but can also be easily removed from the pads for drinking on the other. Thanks to smart nano-gel technology, the pads can be removed at any time without leaving any residue, cleaned with clean water and reused as often as you like. This gives you maximum flexibility and you can always use your magnetic glasses wherever you need them or store them rattling-free and securely in the cupboard. The highest quality and Made in Germany are our goal. All plastic collections are tested , tasteless and BPA-free . The high-tech plastic glasses are almost 100% similar to real glass and are also extremely durable, hardly scratch-sensitive and temperature-resistant.
