Where do you buy the wool? Where is the chilazon from?
For our regular tzitziot we use a company called Vitalgo in Italy; for our niputz lishma tzitiziot we use a company called Summit in Israel. The hillazon lives in the entire Mediterranean sea; it turns out the State of Israel does not allow crustaceans to be fished off its coast and so we get our snails from fishermen in Croatia. – Mois Navon
