A magnet is integrated into the base of the plastic bowls. To ensure that the bowls stay in place during the journey, they must be combined with a metal counterpole . For this, we recommend our metal nano gel mat or placemat . This counterpole is not included in the set. The force ratio between the magnetic bowls and the metal nano gel accessories is perfectly balanced, so that the bowls are fixed by the metal counterpole on the one hand, but can also be easily removed from it on the other. Thanks to smart nano gel technology, the mat and the placemat 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 bowls wherever you need them - even while driving. The magnetic attraction means that the bowls fix each other in place and can therefore be stable and rattle-free. can be stacked/stored in the cupboard. We aim for the highest quality and Made in Germany. All plastic collections are tested , taste-neutral, BPA and melamine-free .
