Paintbrush Cover, Lollacup, Cookies

S2 E3: Lori Greiner checks on her investment of The Paintbrush Cover, a convenient way to store wet paintbrushes from Season Five, and throws a curveball into attempts to take their business to the next level. Robert Herjavec meets with Mark and Hanna Lim, the couple who invented the Lollacup to understand why their sales have stalled and how they can be re-ignited. And despite not getting an investment from the sharks, entrepreneur Liz Holtz still finds success with her gluten-free cookies.
