## Description

Zebra sharbo x refill Mechanical Pencil unit, 0.3mm

Review: Excellent! - 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.
Review: ジェットストリーム4&1を愛用していますが、シャープペンは0.3派。 自己責任で、こちらを付け替えて使用。 ジェットストリーム4&1の方のシャープ軸をカットしたり、穴部分を少し広げて抜けにくくさせる工夫がいる。 落とすと芯が折れて詰まることがある為、注意。 パイロット PILOT 替えゴムS HERFS-10 90円を購入し、針金２本入っている物を使って詰まりをとっています。

## 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?**

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

初代の、000円のシャーボに付けて、使用しています。ゼブラさん。ありがとうございました。初代のシャーボのシャープペンシル部分は、何故か芯が折れやすいので、交換しました。折れなくなりました。古いシャーボを、持っている人は、交換した方が良いです。 芯サイズ 0,3㎜ 0，5㎜ 0，7㎜ の3種類あります。交換出来ます。自分で、引っこ抜いて、差し替えるだけです。
