Does it fit? Are you worried about it in some way?
It looks the same as the "old" Skycig carto. Maybe that's what it is?
Does it have the Blu logo on it?
Blu seem quite happy to sell their out of date cartomizers to customers. GrimmGreen bought a disposable that was over a year old and tasted rubbish. Blu then complained that he gave it a bad review, instead of trying their new "pro" e-cig.
Maybe they should stop selling all their products until they get a bit more organised?
