I needed an easily available light weight tooth brush for a twenty-eight mile backpack this past Labor Day.
The hospital I work for stocks small ziploc bags of patient's toiletries: cheap toothbrush; small tube toothpaste; travel size mouth wash; cheap plastic comb; hotel sized soap bar. I checked the bin for an incomplete set that had the toothbrush. I asked a nurse's permission and I was the proud owner of a toothbrush named China!
It has traits that are not so dissimilar from a female Hollywood celebrity: super thin, not much of a head, but most satisfactory for cheap weekend getaway.
Best part: .1oz or 5 grams on my Pelouze.
Can anybody beat that for a standard
length brush?
P.S. My home toothbrushes weigh in at .4 oz or 14 grams.
