sounds sweet hektik, i seen sum of them pipes now, im in mex right now in a¨cyber cafe¨ one of my cousins is a big drinker and doesnt mind taking me around to the different headshops around mex, but i dont see many pipes with carbs, r they suppossed to have carbs? or will the ones with a screen work? these rnt made out of glass, just some wierd material, i asked one of the guys what they are made of and he told me it was made of some paste that hardens in an oven, will those work?
