Knock Knock was founded in 2002 with the goal of making witty, intelligent, surprising gift and stationery products. Since then we’ve expanded our line again and again, into books, accessories, office products, and more. We’ve recently enjoyed bringing our off-kilter sensibility to kids, showering the shorties with activity books, pads, and travel bingo.

And then, there was Clump-o-Lump! In the fall of 2010, while guest-lecturing at Pasadena’s famed Art Center College of Design, Knock Knock head honcho Jen Bilik met Max Knecht, an insanely talented industrial design student. Out of a vintage suitcase he pulled the first hand-sewn Clump-o-Lump prototypes, about as charming then as they are now. Jen was smitten and we quickly acquired the line from Max.

Everybody who came into contact with Clump-o-Lump fell in love—in fact, no new product was ever so unanimously embraced within the company. In the end though, Clump-o-Lump did not resonate as much as we’d hoped, so we’ve made the difficult decision to discontinue the line.

Thank you to those who supported and loved Clump-o-Lump. If you have any questions about a purchase you made, please don’t hesitate to contact us.
