Heat Reactive "WOW Mugs Heat reactive mugs are a great choice if you want promotional items that have a unique and attention-grabbing design feature.

When the mug is filled with a hot beverage, the specially-created inks used in the printing process react to the heat, and dynamically change color to reveal a new message or image. Photo Mugs and Metallic Luster Mugs These The metallic luster mugs take the process one step further. A gold or silver metallic-look coating is added to the design during printing. The final result is an eye-catching mug with vibrant colors, and a metallic sheen over the entire surface.
