Knock Knock (Geschaffen): Knock Knock Vouchers for Dad

Knock Knock is an independent maker of clever gifts, books, and whatever else they can think up. Their mission is to bring humor, creativity, and smarts to everyday life. Put the fun in functional with #knockknockstuff, and satisfy all your witty needs at knockknockstuff.com. Knock Knock's crackerjack in-house team creates products and develops books from the ground up as well as collaborating with outside authors and other creative types. Whether producing sticky notes or a volume of thoroughly researched nonfiction, Knock Knock happily dispenses irreverence, wordplay, and wit from its sunny perch in Los Angeles, California, to folks around the globe. In January 2018, Emily McDowell & Friends joined the Knock Knock family to form the Who's There Group. Now one groovy Los Angeles team working together to make both brands happen.
