Unfortunately, I coudn't find it in any retail stores or online shops. I think marzia de servi is not the counter product, you can only buy it from beauty salon, but I don't know which salon is selling it. May be you can contact their agent in HK: Super Main Ltd and ask where you can buy these products.

If you are the customer, just want to try one or two items, the only way to know more about it from beauty salon, but if you want to sell these products online or in somewhere, directly contact the agent and get the wholesale price but they don't accept the small amount.
