here are 3 great washable hoses:
the first one is a razan, its from nazarhookah.com. its cheaper than the next hose and you can choose a different colour for the handle, and the mouthpiece detaches. other than that its pretty much the same thing as this hose...
this one is from hookah-shisha.com. its a few dollars more expensive than the razan. the handle and the hose are the same colour and the mouthpiece also comes out. this next one is alot different than these 2 first ones..
this one is also from the same site as the nammor. its ENTIRELY washable (its made out of all plastic). its very light also! and although its not as wide as the nammor or razan, it does have a fairly good pull to it (just ask sambooka!). the sad thing though, this hose doesnt look that stunning or nice to look at so a hose cover would be a good addition. also its alot cheaper than a razan (21 bucks), or a nammor (23 bucks), this hose costs only 7 bucks.
