Underbutter is our version of wood conditioner, made with organic beeswax and oil. We provide one of these tins with each vape in the standard kit.
You can apply it to your vape whenever you want. We recommend warming up your piece and using a lint-free cloth such as t-shirt material to gently rub a little of the butter into the wood grain. Be careful not to get too much around the heat port or plug. If you do, no big deal - it will burn off with time. Check out our How To Video on YouTube.
