From Tiki Farm:

"A piece of cut bamboo that is a ceramic Tiki Mug! The "Steely Dang! green satin glaze gives this mug an interesting yet natural look. Standing 7-1/2 inches tall x 2-3/4 inches in diameter and holding about 12 ounces this mug will be cornerstone in your collection.

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.
