It is a lovely mug. The actual mug is shiny and smooth. Very nice quality. It was everything I expected. Zazzle has so many nice mid century modern designs to choose from. All so pretty! The design was very clear and looked expensive.

This design is full of browns, pinks, turquoise and more. Very contemporary with vivid geometric triangle shapes. Looks really great with our Mexican tile tables. Really stunning, modern pattern! The lines for each triangle are perfect. The colors are vivid and pop. Great Printing.
