This is put out by the lovely people at Envy cigs and they have a lot of awesome little vaporizers and mods for e-cigs as well. From what I'm told, you can also drip e-juice with the e-juice attachment. Unfortunately, I moved a lot of my stuff around at home and can't locate the extras that were included (all in the theme of "stealth" - a disco ball stash keychain, a silicone key fob stash, etc...) but there's so much great stuff on their site, you should check them out!
Here's a linky to the Trickster pen - it's actually on sale right now, 50% off - showing $49.95 as of the date of this posting.
And as always, don't forget to check out my website - http://www.lindareviews.com and like me on FB - most updates go on there and twitter.
