Will do. naturevape.co.uk the 22/24mm versions seem to come and go quickly but the 17mm is generally in stock in a couple of colors. Spare parts are available and shipping from UK -> USA was 4-5 days.
There doesn't seem to be a lot of buzz around this mod outside of ukvapers--not sure why, is a nicely put together mod--anyway...
Here is a picture of gizmo/Penelope I found on ukvapers forum. Obviously its possible..but wondering if it fits as is or if this person had his Penelope turned down to fit--will report findings.
Cheers
