The Uwell Aeglos P1 Kit is intended specifically for use with the Uwell Aeglos P1 Cartridge. It is made of PCTG food-grade safe material, has a 4ml capacity, and is simple to refill. The Uwell Aeglos P1 Cartridge is coil-free but works with the majority of Uwell Mesh Coils, which improves flavor and makes for a great DTL vaping experience. To change the coil, simply plug in and unplug—it's simple and convenient. The Aeglos P1 Pod's strong magnet at the base provides a flawless fit with the mod. featuring a silicone plug to seal off the bottom refill. The pod must first be taken out, turned upside down, and the silicone plug must be opened before filling. 1 piece per pack.
