V3 inserts have longer & tighter top tapers to increase air restriction & thinner walls + bottoms for bigger clouds!
3mm larger diameter than the carta stock insert & a tapered top lip to prevent splash over and fit snug in the atomizer screw on lid.
Comprised of thousand of tiny air bubbles trapped within the quartz. The textured surface creates thousand of peaks and valleys (nucleation sites) to assist in vaporization.
American Made in Denver, CO with American & German quartz.
