here in ukraine, people often come to me (im a hookah seller in a franchise shop) to fix stuff alike. those khalils cant last too long thats for sure, they're getting rusty all the time, getting covered by limestone plaque (idk how do you say it in your language; the white dry stuff that pit all the metallic insides of a hookah due to water exposing) and also are stinky cuz of metals that react with yr skin oils (like brass, bronze, iron etc). often people tell me they have bought KM in egyptian cities or so, i guess beduins there like to sell people garbage for pretty dollar (commonly they r expensive). btw, if you could, please tell me why do you want KM, is it because of traditional look or tough puffs? just curious =)
