Toothbrush + Toothpaste In One!

nice concept, but in the long run it'll get clogged with toothpaste and be rather disgusting after a few weeks

Unsanitary. Imagine your saliva or backwash getting clogged in the tube overnight and then having to brush your teeth the next day.

i thought that was pretty stupid

It probably closes and opens instead of just squeezing out

This is a real thing, you know. My brother uses one, works fine.

That's a nice toothbrush.
Would be a shame if someone were to ejaculate into the reservoir...
