Pentel Energize-X 0.5mm - Violet

I've been looking for a reserved, modest-looking mechanical pencil to be used in public places and offices. This mechanical pencil has many qualities I am looking for.
- Light weight
- The pencil has a tip that can be fully retracted to avoid damaging papers, fingers and canvas-based pencil cases. Most mechanical pencils available on the market have tips that are long and protruded like a syringe, and they cannot be retracted. Being able to fully retract it is a major selling point for me.
- Elegant shape. The pencil is straight (no curve mid-way), and the surface is mostly smooth without unusual pattern.
- Upper tip has a plastic cap to prevent the refills from falling out.
- The pen has a dark appearance and without any large surface that has a cheap silver metallic appearance, unlike most mechanical pencils.
- The pencil comes with a pocket clip.
- The product name printed on the clip is modest and not fancy.
