Zebra F-301 ballpoint pen hack

Without further due, here is a hack replacing the Zebra F-301 F refill with the one from Uni-ball Jetstream 0.5mm. Get the smaller Jetstream refill, usually the one to refill the Uni-ball multipen.

See that the Uni-ball Jetstream refill is the same length as the Zebra F refill.

The next step is to open the black cap from the F refill. This is easily done using your nail. Then you’ll have to take out the refill from inside the barrel. This also can be done by hand, just push down-up.

Push the inside, from the tip towards the upper end.

Next, you’ll have to do a hack to put the Jetstream refill into the F refill barrel. You can use your creativity. What I did was cutting a bit of the black cap from the F refill, and some part of the Jetstream plastic (same length), and then wrapped the middle with some tape, to keep its position in the barrel.

You have to sacrifice the black cap here. However you can do other hack, limited only by your creativity.

Now put them altogether into the F-301 body, and Voila! This is better and cheaper than my Parker.
