From Tiki Farm:

"The rich green, blue and brown glossy glaze adds to the realistic natural look of this classic design. We think it looks like a cascading tropical waterfall! This popular mug design stands 7-1/2 inches tall x 2-3/4 inches in diameter and holds about 12 ounces.

Please note: our dual-tone glazes have variance and no two mugs ever turn out the same."

This same design was issued in multiple glazes and also branded for different tiki locations.
