ERIC PRUM and JOSH WILLIAMS have been best friends since they were freshman roommates at UVA. A decade later, they are founding partners in WandP Design, a product innovation company launched in 2012 with a Kickstarter campaign to manufacture a Mason jar cocktail shaker. Their $5k ask resulted in $75k of funding, and in less than a year they have sold more than 100,000 units of The Mason Shaker in 4,000 doors in the US and internationally. The WandP product line includes more than fifteen bar items under The Mason Shaker brand, and, by the end of the year, their portfolio will include 35 items. Eric, Josh, WandP Design, and/or "The Mason Shaker" have been featured in the New York Times,… Martha Stewart, Southern Living, Food and Wine, and on CNN among other media outlets. Eric and Josh host cocktail events at cool places, such as Momofuku, Haven's Kitchen, the Tasting Table Lobster Roll Rumble, and at retailers. They are guest cocktail contributors for marthastewart.com.
