Okay, this is my first mod and tut. so I'll be needing constructive criticism.
THIS PEN CAN NOT WRITE!!!! Fair warning, but onward with the tutorial!
Name: Zebra F-301 RTS
Length: 22cm give or take
Weight: F-301 ~ RSVP CX
Pens Needed:



2x Zebra F-301
2x Papermate med pt.
2x Signo 207 retractable (optional)
Tools needed: Pliers, Super glue, something with which to get the clicker part out, knife or something to cut soft plastic.
1. Using the pliers, pull off the little ring (in this case black) off of the back of both Zebras. Be sure to pull up not back, If you pull backwards and bend the ring, it will break and waste a pen.

2. After completing step 1, something like this should slide out, cut directly in the center of the hole.

3. Put a small amount of super glue around the rim on both sides of the barrel and slide the pieces from step 2 in.

You should now have this

4. While it's drying, it's time to get your caps ready. Slide a pencil eraser into each of the caps. After that, grips and tips. This is where the Signo retractable comes in. This tip clips onto the cap and stays on. If you don't want to use it then use another metal tip of your choice. Apply the grips you want, I use half a BIC Permanent Grip marker and half a RSVP, then add a G2 for the sake of looks.
5. Spin Away!!!
Final Product -

Pros: Heavier than BICtory
Slightly longer than average BICtory
Looks nice
Spins nice
Cons: Economically, this pen makes no sense. It's 2 (possibly 4 if you use the Signos) pretty expensive pens to make one spinning pen.
Again, it does not write.
