IVG Salt Liquid 4-in-1 20 mg is a pack of four nicotine salt e-liquids designed for use in mouth-to-lung (MTL) vape kits and pod systems. It is made by IVG (“I-Vape-Great”), a UK brand known for producing a range of vape juices with balanced flavours. 

<> Key Features & Description
Nicotine Type: Nicotine salts — smoother throat hit and faster absorption compared with freebase nicotine, especially at higher strengths. 
Vapestreams
Nicotine Strength: 20 mg/mL (≈ 2.0% nicotine) — stronger level typically used for satisfying cravings with smaller amounts of vapor. 

Bottle Pack: Four 10 mL bottles in one pack → total 40 mL of e-liquid. 

VG/PG Ratio: 50 % VG / 50 % PG — balanced mix for consistent flavour and suitable MTL vaping. 

Vaping Style: Mouth-to-lung (MTL), which mimics the inhale style of smoking a cigarette. 

Packaging: Childproof caps and easy-fill nozzles on bottles. 
<>Typical Use
This type of e-liquid is intended for use with refillable pod systems or low-wattage MTL vape kits — not high-power sub-ohm devices. Nicotine salts at 20 mg are formulated to deliver a smoother experience even at this strength, compared with conventional (freebase) liquids.
