product is of great quality, i have been using this on my products with good outcome so far. great product indeed.

Quality： Excelent quality, i test them here in Chile and they deliver 30% more than the package claims, really really good, and the price is really unbeatable, i saw in USA, korea and japan, but still buy them here, way better value than the competition. Service： The seller has to be one of the best in the industry, i asked for the MSDS and not only he gave it to me, he also gave me the "REACH report" which i didnt know was something i needed. Also he was always there when i needed him and very keen to answer absolutely everything.
