Questions we are asked about MTL versus direct-lung style

What causes a burnt taste with Vape Sourcing vape pen?

Nine times out of ten it is priming. A coil that has not been saturated before first use, or a tank run dry, will scorch the wicking and that taste does not go away. Fitting a new coil and waiting a few minutes before the first draw prevents it entirely.

Does Vape Sourcing vape pen need any accessory to be usable on day one?

In most cases no, it is usable straight away once charged or filled. The two things worth adding at the point of sale are a spare coil or pod and, for removable-cell devices, a proper storage case.

Can Vape Sourcing vape pen be shipped to the UK without extra paperwork?

Standard commercial documentation is enough for most consignments, but the buyer is responsible for the import side. We supply invoices, batch records and compliance paperwork with every case so the clearance step is not where a shipment stalls.

What is the realistic wholesale margin on Vape Sourcing vape pen?

Most retailers work to a target of 50 to 61 percent at the counter, with the figure moving up when accessories are bundled. Margin per shelf metre is the better measure, because a fast-moving line earns more than a high-margin one that sits still.
