An elegantly hand -cast magnet is integrated into the base of the crystal glass. To ensure that the glass stays in place during the journey, it must be combined with a metallic counterpart . The set includes a metal nano-gel pad for this purpose. The force ratio between the magnetic glass and the metal nano-gel pad is perfectly balanced, so that the glass is held in place by the pad on the one hand, but can also be easily removed from the pad 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 you like . This gives you maximum flexibility and you can always use your magnetic glass wherever you need it or store it rattling-free and securely in the cupboard. Our aim is to provide the highest quality and be made in Germany. All crystal glass collections are made of the finest Tritan composite , tested , scratch-resistant and BPA-free .
