Uwell Caliburn GPP Side Fill XL Cartridges are the refillable cartridges for the Caliburn GPP: a higher-capacity XL cartridge with a side-fill port, sold as 3-packs in a box of 5. The customer fills them and replaces the cartridge as the coil wears, so like any Caliburn pod this is a repeat consumable, here for the bigger, higher-power end of the Caliburn range rather than the small MTL pods.
For a shop, the GPP cartridge is the reorder behind that device. The XL cartridge holds more, so the customer refills it less often, but it still wears out, so it stays a steady repeat. Stock it where you sell the GPP, and match the fill style, since it comes in a side-fill and a top-fill version.
Five packs to a box at three cartridges a pack, so a trade box is fifteen cartridges: divide by five for the per-pack figure, or by fifteen for the per-cartridge. A refillable cartridge is a repeat reorder as the coil wears, and the XL capacity suits the higher-power GPP user. The Caliburn range has broad demand, so its cartridges earn a facing beside the small A3S pods on the refillable vape pods shelf. They take any nic salt or freebase the customer fills them with, and sit on the vape accessories line.
The GPP Side Fill XL cartridge fits the Uwell Caliburn GPP, the larger, higher-power end of the Caliburn range, so it serves a customer wanting more capacity and a looser draw than the small MTL pods give. It is the side-fill version; the top-fill XL cartridge is the same capacity with a different fill port, so match the fill style the customer prefers. It is device-specific, so match the cartridge to the GPP before selling. It is not for the small-pod MTL vaper, who wants the standard Caliburn pod, or the disposable buyer. The Uwell range gathers the brand.
A counter that sells the Caliburn GPP should stock its cartridges, since the device drives the cartridge reorder. A shop with no GPP trade has less call for them, though a Caliburn counter often carries the range. It is not a standalone impulse line. Stock the fill style your customers ask for, keep the device in stock, and reorder from the pulls. The wider Uwell range gathers the brand.
