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 Pad Can Be Removed At Any Time Without Leaving Any Residue, cleaned with clean water and reused as often as they like. This gives customers maximum flexibility and they can always use their magnetic glasses wherever they need them or store them rattling-free and securely in the cupboard. The highest quality and Made in Germany. All plastic collections are tested , tasteless and BPA-free. The high-tech plastic glasses are almost 100 percent similar to real glass and are also extremely durable, hardly scratch-sensitive and temperature-resistant.
