@octothorpe @morrick That reminds me -- I've had this NeXT Cross pen for about 30 years. It was a gift from someone related to a NeXT employee. Haven't used it in probably 20 years at least. The plastic over the logo used to be clear but it's yellowed with age.
It doesn't write, maybe because I used a cheap knockoff ink refill. I'm going to Staples today anyway. I think I'll pick up a new refill.
