## Description

rOtring Four-in-One Ballpoint Pen Black, Red, Blue + 0.5mm Mechanical Pencil

Review: Well Made & Practical - I was amazed on how well this pen is made and how practical it is. 3 pen colors plus mech. pencil in a solid metal design with an amazing mechanism to choose the colors from. Truly recommend this product.
Review: Expensive but high quality - I have been using this writing tool for the past several months. its quality is obvious and all of its component pieces fit together perfectly. It has a nice weight to it but I don't think its too heavy. Also I was a little worried about its diameter and how well it would fit into my hand. Its really not much bigger than my other mechanical pencils and does not at all feel awkward. The selection method works great and I can always select which pen or pencil I want. I actually took the thing apart to understand how it works. Retract the nib by pulling up on the clip. It is spring loaded and makes a nice click when it retracts or extends. To select a pen or pencil retract the nib and then place the tool in a horizontal position and rotate it until the picture of the pen/pencil you want is facing up. Then just push the plunger and out comes the selected nib. This tool is so well built I expect it to last for my lifetime. I am happy with my purchase and I would buy it again.

## Questions & Answers

**Q: Would I be able to replace the 0.5mm Mechanical Pencil for a green ink replacement?**
A: I've ordered replacement ink tubes, as well as the pencil tube. They are all the exact same size, so I cannot see why it would not work.

**Q: Is it as smooth as the 800**
A: I am not familiar with the 800. But, the pen works great and it feels quite smooth to me. It was a great purchase.

**Q: Can it write upside down (is ink pressurized?)**
A: No.  The refills are not pressurized, and it won't write upside down (at least not for more than a couple of seconds).

**Q: Is this a gravity controlled pen?**
A: I'm not sure but I do know that how you hold the pen facilitates what color you want it to write in. It is pretty unique in that regard and I'm sure gravity some how plays a part with how the positioning of the pen causes the pen to write in the appropriate color(red, black, blue, pencil)
