I had a customer asking today if I could make a pen that uses a Tul refill. Has anybody tried this, before I go buy a Tul pen to tear apart and measure the refill?
I had never of them until I gave my friend his mammoth tooth Triton and he asked if the refills that he had for his tul pen would fit so we looked and the refill went right in to the Triton and fit just fine. But then he wrote with the schmidt and really liked it also.
But those are the only ones I have ever seen.
