First off, the customer service is truly wonderful at K2. You send an inquiry, they answer your questions quickly and efficiently. I ordered the 5K medals and had our non-profit's logo engraved on the back of each medal. K2 sent me a proof of the medal engraving for my approval before printing them. After my approval, I received the medals very quickly. They turned out AWESOME! Very nice product and the engraving was flawless! I will definitely use K2 Awards for all of my award needs.
