Black, white & silver have been the dominant colors of electronic devices for several years. High-quality individuality has so far found its limit in the selection of suitable cases. But now you have a choice. Defrey Customizing offers you the opportunity to color-refine your electronic devices as required. You either send in your old device or buy a new one from Defrey Customizing. For business customers, on the other hand, completely new opportunities for advertising and representation opportunities arise.
