Kong, Iran - Several wooden Lenjs are under repair at one of the only left wooden Lenj workshops at Kong, Iran. Several years of experience is needed for workers to learn the skills needed for building traditional Lenjs. Despite decreasing demand for brand new wooden Lenjs, due to high material and construction costs, people sometimes invest in the older Lenjs, even the ones that can't be used for trading purposes, and repair them to be used for tourism.
