This version of WAHA NUI "the big mouth" is glazed in maroon brown (gloss white glaze interior) with a Santa's hat lid in a red glaze (the hat has no straw hole, because it's not washable). The mug is shaped like a Tiki head with a large crescent shaped smile lined with large squarish teeth. Sold only at Custom Parts & Wear X-Mas party in Mellingen (Switzerland) Saturday the 22nd, December 2012.
