ProNic was developed to put an end to low quality, harsh nicotine shots that prevent the consumer enjoying how their liquid should taste. Using the highest quality nicotine, VG & PG we have manufactured the smoothest nicotine shots on the market. TPD constrictions have changed the industry standard for bottle size, 10ml when containing nicotine. Now we see a wealth of 0mg nicotine liquids in bigger bottles on the market, allowing the user to add flavourless nicotine themselves after purchase, these are referred to as ‘short fill’ bottles. This will often be a 60ml size bottle with 50ml of liquid, or a 120ml size bottle with 100ml of liquid. Simply remove the nib / cap and pour in your ProNic to reach your desired strength.
