I didn't mean to type refillable, I meant disposable 😉
With that in mind I would give the reason that its conveniant to throw away and get another already filled and ready for a needle........
And in terms of malfunctioning pens, vial pens can break just as easily and if you dont have a spare one, or hypodermics your screwed.....but I havent used all brands of vial pens and in the time I have been using disposables pen technology may have come on a bit.....
