A beautifully hand-poured magnet is integrated into the base of the plastic glasses. To keep the glasses securely in place while driving, they must be combined with a metallic counterpiece. The set includes two metal nano gel pads for this purpose. The force balance between the magnet glasses and the metal nano gel pads is perfectly calibrated, so the glasses are fixed by the pads on one hand, but can also be easily lifted off the pads for drinking. Thanks to smart nano gel technology, the pads can be removed without residue at any time, cleaned with clear water, and reused as often as desired. This gives you maximum flexibility to use your magnet glasses wherever you need them or store them securely and without rattling in the cabinet. Highest quality and Made in Germany are our standards. These glasses are made from high-quality Eastman Tritan™ Renew – a premium plastic with certified recycled raw materials. The material is BPA-, BPS-, and bisphenol-free, features brilliant glass-like clarity, is taste- and odor-neutral, and is especially resistant to breakage, scratches, and temperature. Eastman Tritan™ Renew thus combines the elegance of glass with the robustness and durability of a modern high-tech material.
