The zirconium beads having a uniform consistent quality inside and outside, there are many similar products on the market rely on for a long time to get a lighter polished surface, but use over time, after the destruction of the surface light layer of aging, performance is a significant decline, win Chi products are completely not the problem, it is the ideal choice to replace imported products.
