Lori Greiner checks in on her investment of The Paintbrush Cover, a convenient way to store wet paintbrushes from Shark Tank Season 5, by visiting the creators, John and Sal DePaola and Anthony Caputo, from Jackson, NJ. She throws a curveball into their attempts to take their business to the next level.

Robert Herjavec meets with Mark and Hanna Lim from Altadena, CA, the couple who invented the Lollacup – an innovative sippy cup from Season 3 – to understand why their sales have stalled and how they can be re-ignited.

And despite not getting an investment from the Sharks in Season 4, Warren, VT resident Liz Holtz, the entrepreneur behind the brand of Liz Lovely gluten-free cookies, still finds success even with overcoming personal struggles.
