All Flavoring Available at: http://shop.perfumersapprentice.com/c-54-professional-diy-flavors.aspx Menthol Crystals were crushed than I filled 3/4 of 120ml bottle with powder than filled to the top with pg. 3% Wintergreen 1.8ml 3% Menthol 1.8ml 3% Koolada 1.8ml 5% Spearmint 3ml 86% 50/50 Nic base 51.6ml Total=60ml This is a cool, smooth, non overpowering menthol vape. I use to smoke Newports and have tried a bunch of commercially available e-liquid flavors and didn't like any of them. I've tried mixing all the available PA tobacco flavorings and realized what the problem is. Cigarette tobacco is gross, I can't stand the flavor any more. This is my new favorite all day vape. I've wasted enough money on Flavour Art, Lorannes, Tasty Puff, and Perfumers Apprentice flavoring, about $300. This is the best mix I've tried to date.
