These bamboo toothbrush sets from Izola are surprisingly beautiful. Sets, you say? That's right: sets. Izola sells toothbrushes in sets of 4 to 16 so that you're reminded to switch them up at proper intervals (every 3 months). They're even numbered! You can buy the toothbrushes a full year's worth at a time for family sinktops, or in gift sets for guest bathrooms. We love the eco-friendly materials used in these beauties, and appreciate that Izola has made tossing our old brushes foolproof.
