Longfills FAQs
- What exactly is a Longfill? A Longfill contains 20 ml of 0 mg/ml flavour concentrate in a 60 ml bottle, designed to be mixed with nic shots and VG/PG to reach your preferred strength and ratio. Do not vape the concentrate on its own.
- How many shots can I add? You can add up to four 10 ml shots; this allows 0–≈14 mg/ml depending on the shots selected.
- Are Longfills TPD/TRPR compliant? The concentrate itself is 0 mg, so the 10 ml / 20 mg/ml caps apply to the nicotine shots you add.
- How is this different from shortfills? Shortfills are pre‑mixed 0 mg e‑liquid with less headroom (commonly 50–100 ml total), usually yielding ~3 mg after one 18–20 mg shot; Longfills provide more flexibility on strength (0–≈14 mg/ml) and PG/VG.
