This is a 1mm thick insert for huge clouds in the FocusV Carta! Works with any carb cap by best with the marble spinner in my opinion.
Or get the all new Extra Large quartz! This is the largest possible quartz insert that will fit in the Carta, and it works great! It greatly reduces or eliminates splash, which is a big issue with the original quartz. Upgrade your Carta with the new XL Carta insert, you will love it!
*** these fit great with the original atomizer top and my titanium everlast atomizer top. But 1 person with the new ceramic atomizer top said the fit was a little too tight with the new design recently. It may be best to pair these with a non-ceramic atomizer lid. I do have them available if needed***
