1.Medical grade glass protects and maintains the original purity of extractions, making user enjoy pure vaping;
2.The adoption of larger oil intake hole size and dual-coil avoids burning taste. Different oil intake oil sizes:0.7/0.9/1.2/1.6mm make oil of different thicknesses vape in the heating core more smoothly and freely, while dual-coil design enlarges the heating area, achieving abundant vapor without burning taste.
3. Dual-seal design controls the leaking rate. Our brilliant R&D colleagues designed this structure at a proper position of the cartridge after countless trials and failures. Therefore, we controlled the leaking rate eventually.
