About Us "We set out to create a premium spill proof snack cup for children, by combining ingenious design with the highest quality materials. We think you&＃039;ll love the result." Phil Amormino, President, Witty Works, Inc. Witty Works, Incorporated is a family owned and operated business located in Sonoma, CA. Munchie Mug, the original invention of Witty Works, was first conceived of when Phil Amormino and his daughter Amy watched her son Grant spill yet another "spill proof cup" full of cheerios on to his carpet. Phil, a machinist and science teacher by trade, knew with with the help of his family, he could invent a snack cup that was innovative, safe and truly worked. We place the safety of children above all else so, keeping that in mind, we took years to perfect both the materials and design of our cup. We pride ourselves on using safe materials that are third party tested and we are committed to always making our product in the USA.</p>
