Nic Up does one job across the whole ratio range: the 18mg nic shot that turns a 0mg shortfill into a vape. The four lines cover every bottle you might sell, a 50/50 and a 70/30 for freebase shortfills, a 70/30 Ice for menthol blends, and a nic-salt shot for smoother made-up bottles. All ship as a box of 10.
Match the shot ratio to the shortfill and Nic Up covers a shop from one brand. Stock the 50/50 and 70/30 as the everyday pair, add the Ice and the salt shot where your bottles call for them, and rack the lot beside the shortfills so the attach never gets forgotten at the till. These are cheap and low-margin on their own, but they protect the much larger bottle sale, which is the only reason to carry them. No shortfills on the shelf means no need for any of this. There is no minimum order, so a couple of boxes is a fine start, and the wider liquid range sits on the e-liquid wholesale page.

By the box of 10. Each is a 10ml 18mg booster, in 50/50, 70/30, 70/30 Ice and a nic-salt version. There is no minimum order, so a single box is a valid order.
Match the VG ratio. Use the 50/50 for mouth-to-lung mixes, the 70/30 or 70/30 Ice for sub ohm and menthol blends, and the salt shot for a smoother throat hit. Most 100ml shortfills take two shots for 3mg.
