They always have great displays at Paul Smith. I feel pretty strongly that with your toothbrush it's better to go with quality over style. Don't screw around with oral hygiene.
I'm sticking with a Spinbrush (now curiously owned by Arm & Hammer) or an Oral B because they're the best. But if I was deciding on style alone I'd go with one of these colorful brushes. I should get a few spare ones for the country house or the private jet for guests who forget their toiletries.
