Good idea; needs work
I like the bristles; the handle is awkward.<br /><br />These bristles seem firm enough to clean well, and they're tapered to a soft point that doesn't irritate my gums.  However, the flat handle seems ergonomically clumsy.  The head is more bulky than that of a plastic handle.  My lips don't seal well against the handle's square edges, so I tend to drool toothpaste on my shirt.  (Sorry if that's too much information.)  And of course the texture is bamboo, not plastic.  I like them well enough to continue using this pack; however, I may not buy more of them.
