I like those hang tags on threads although I would expect they might cost more than the others mentioned.
But the best of all is a tag that is easily viewable by a possible buyer. Not just for pen shows but overall I wish that the price was easily viewable. I would rather not waste a sellers time asking to pull pens jif knowing the price up front would stop me.
I guess it is just society as a whole moving away from paper and ink based information collection to one of bits and bytes. I use cursive but mainly when I write letters. My daily use of information requires either block letters or a keyboard. It may be sad that cursive is no longer being taught but to be honest I would rather teachers focus on logic, math, English and history. It seems to me the ability to create a thought and transmit it to another person is much more important than the medium it is sent in.
