Mouthpiece Care and Maintenance

We recommend handling and cleaning the mouthpiece with particular care, as its precious metal coating,
24K gold or 999 fine silver, is delicate and requires special attention. Avoid abrasive products,
harsh chemicals, and excessive rubbing to preserve the shine and beauty of your Frate Precision mouthpiece over time.

Thanks to the most recent technologies based on CAD-CAM software planning during the productive process and to the product making with CNC machines,
we are able to guarantee any mouthpiece can be reproduced with centesimal tolerances.
