Jewel Mania is planning to cooperate with the international violin festival ViolinFest, which is also the Omni-client. The cooperation involves the production and sale of special jewelry souvenirs, intended to sell at concerts and other events of the festival, as well as through the Internet, and a special exclusive collection Violin Fantasy. We ask experts to share their thoughts on how to implement these plans more efficiently and profitably for both parties, and what other areas for cooperation may be between Jewel Mania and ViolinFest.
