I believe the seller is purchasing the juice directly from the Pen's outlet outside of London. That is why the bottles come without boxes and usually have no bow on the lid. The juice itself, though, seems to be legit based on the two bottles I purchased from him back when my FAD was a mere glimmer in my eye!
Trahit sua quemque voluptas - Virgil
He saw a lawyer killing a viper on a dunghill hard by his own stable; And the Devil smiled, for it put him in mind of Cain and his brother Abel.
