Bumper Smooth is designed to take the edge off the throat hit that is unavoidable with certain flavour profiles or high nic liquids. Throat hit reduction is a science in itself and a very complex problem to solve. Although it is not possible to eliminate completely, our proprietary formulation will help reduce the effects of throat hit by as much as we possibly can, with as little as possible impact on the flavour.
The marking system is calibrated for use with a 60ml unit, but we have crammed enough smooth voodoo magic in this small bottle to use up to a 120ml unit. 30ml bottle? No problem! simply use half the recommended amount.
