## Questions & Answers

**Q: Can you use them without the pen?**
A: ... if you can hold the 70 mm length x 1 mm dimeter pen, why not?  ... but why?

**Q: Does it comes with lead?**
A: Yes comes with a lead.

**Q: Does this fit the sharbo x st3 multi pen?**
A: I believe it will.  The “guts” of the Sharbo line are all the same. The ones I have are .5 mm.   I also stocked up on the red and pluck pen refills.

**Q: Can you refill lead holder with lead without purchasing a new cartridge?**
A: Yes, you can use leads to load this cartridge.

    Excellent!
  

*by O***D on Reviewed in the United Kingdom on 13 January 2019*

Does the trick.. 0.5 mm lead is too thick, but  .3mm lead snaps too easily. Would have prefered. 4 option but this is fine.
