Good prophets has them. (Just put "cone" in the search box.)
The pink and purple ones I got from him were the long ones, but you could email to make sure they still are.
The black he has says "matte"

Edit: That's wrong. I got my pink one from good prophets and the purple one from altsmoke.
AltSmoke.com - Riva Ecig Ego He also has black.
Either way, I'd email and ask before you buy it.
Thanks! Didn't realize they did colors besides black either, looks like I can match the cones to my batteries after all. Just not a fan of chrome and until now it was all I kept seeing.
