I am relatively new to fountain pens, so don't have a big collection of empty pens on hand. I recently ordered a few samples of ink from Goulet Pens, but was only able to try out 3 of 5 due to my lack of suitable pens. I am attempting to find a "signature" ink in my favorite color of teal and am slowly working my way through my collection of samples.
I had an idle thought today that I could order several Platinum Preppy pens, transfer all the ink from a sample vial into a pen, then immediately be able to make a writing sample, but also leave it in the pen for storage (labelled in some way of course). As one of my daily use pens runs dry of its test ink, I can use a syringe to transfer ink from the eyedropper into it for trial.
Is this a feasible idea? What other options are there for instant gratification ink trials?
