Refills also fit Zebra Sarasa Stick and Sarasa Clip retractable pen bodies, if
you gently remove the small plastic thing at the end of the refill.
Unfortunately I've had two Signo Bit pen bodies crack where the body screws
together. I could not fix it with glue or tape, but the refill was brand-new
(and I luv the Bit!) so I tried to fit it in many different old pen bodies. I
did notice the ink dry&scratchy when I used a Sarasa Clip body because this type
of pen is meant to be protected by a cap when not in use, but the Clip is
retractable, no cap.
This pen is my absolute favorite. I consider myself a pen junkie- I've always
loved pens and have had a fascination with them. When I discovered thinner
Japanese pens, I fell in love. The thinner, the better. This pen was the
thinnest I ever found, and wrote like a dream.
It takes some getting used to- at first, it feels almost scratchy because the
tip is so incredibly fine. With a gentle and light hand, however, it writes
beautifully. Something about the superfine tip makes ugly chicken scratch even
Unfortunately it's discontinued now, but if it ever comes back in stock, I'm
buying like a million of these refills. They're the best.
