Get a pump!! ha ha… or, see if they’ll reintroduce the original novopen – ahh, a thing of brushed metal beauty.. not like the plastic crap they dish out these days.. never had an Optipen..
Over the years I’ve had Novopens, a couple of Humapens, ditto Autopens, pre-filled pens (now they really are plastic crap) and just a good old syringe and bottle..
