It's a Silver/Black Grand, I'm very excited and it's working well so far, but I need to keep using it for a few days to break the new AVA Atomizer in and learn how to use an atomizer (instead of my usual cartos) properly in the first place.

(Please ignore the Vmod XL in the photo - I took that to show my GF who also has and and loves the Vmod to show her a size comparison)
One quick question though. What is the small baggie of gray goopy stuff that leaked all over everything else in the big baggie? It wasn't covered anywhere on the instruction sheet and I couldn't really use the search function here because I don't know what it's called.
Thanks!
