Whats with the silicone strip in the pictures? Never seen THAT..

It’s a ‘condensation plug’ you can find it sold on several European and Japanese stores. It’s probably useless but there you go.

Well, since that's the only extra part shown, I'd guess any condensation plugs/air inserts will have to be bought separately, like for any other bridge of this style. I don't know how that little silicone strip will DO anything, but it wasn't included with my Vapeasy version of Crossbow, so I can't guess any further.
