Dollar bills aside, the toothbrush is super eco-friendly as you can replace the head when it gets worn(one extra replacement head is included in the pack). Plus they're manufactured on low-energy machines in the US and the packaging uses vegetable inks and 100% recycled PET plastic.
The bristle heads looks really big too so I'm hoping it'll do a good job. Hopefully I'll also be getting a new tooth polish soon(from here). So I'll have to see whether they turn into a dynamic tooth-cleaning duo...
