Tired Of Dirty Cup Pile-Ups? So Were We! We were tired of the dirty cups that accumulated throughout the day with little ones. As designers, we knew we could do better. That's why we created PhillUp. PhillUp is a simple, beautiful and highly functional kid cup that hangs up on your fridge. Now kids and friends can help themselves. Together we can strip away the clutter and focus on what matters most... our families!
