Gear Review: RADIUS Source Toothbrush

This portable toothbrush is made with recycled materials.

Next trip, scrub your pearlies with a dollar bill. Sort of—the handles of RADIUS’s Source brushes come in blends of polypropylene and recycled cash, flax, or wood. And you can replace the wide, soft-bristled heads when they wear out. (Add a travel case for $3.) $7; radiustoothbrush.com
