Skoai was designed and produced by Falin Minoru (aka, Tiki Kaimuki). The mug is shaped like a skull with deep sunken eyes and nasal cavity. Its four teeth are moais. The edition of 50 was produced in various colors with an additional 15 produced in special custom editions (including the Halloween 2009 version). Measures 6" tall by 5" wide by 6.5" diameter. This Halloween 2009 version was limited to five pieces in a volcanic black glaze with orange moai-shaped teeth. They were not put up for sale all at once in 2009, but made available for purchase a couple at a time over several years.
