The K1 is a new generation of glassomizer, which uses the Aspire “BVC” (Bottom Vertical Coil). This new coil is designed to last longer while still giving users the purest and cleanest taste from e-liquids. The stainless steel drip tip and the pyrex glass gives the K1 a strong metallic impression, which makes it look very clean and high-end. This unique design also makes it easy to carry, install and refill.
