Modify your Boundless CFV convection vape with these heat retention rings! Every type has its own unique style, qualities and flavour.
Rosewood produces thick clouds of vapour. Rosewood complements your herbs with a strong, woody flavour and aroma, whilst keeping the pure convection effects of the CFV intact.
Bamboo has a mellow, subtle taste. Bamboo tends to amplify the flavour of your herb. Just like the rosewood version, the bamboo heat retention rings don't absorb heat, allowing for pure convection vapour production.
Quartz adds a conduction element to your vaping experience. Unlike the wooden ones, the quartz ring does absorb heat, allowing the chamber to heat up faster. The added heat provides more - although slightly less flavourful - vapour.
Every pack contains five retention rings.
Please note: these heat retention rings are only compatible with the Boundless CFV V1.
