There are many kinds of clean tastes, generally there are really clean tastes and fake clean tastes. As far as the truly clean taste is concerned, it contains very low odor and very low odor. Nippon net flavor 120 is a product with very low odor. The so-called fake clean smell is the paint with essence. Although it smells good, it can't meet the requirements of real clean taste. Personally, I prefer Nippon Chunwei 120 series, which is more affordable and more reliable in technology.
