I found my pen

At least for now. This one can seemingly do everything. It’s the Cross Tech 3+.

Simply twist the barrel to switch from black ink, to red ink, to mechanical pencil. Blue ink also is available.

And there’s the plus part, which is that the bottom end includes a nib that smoothly glides across the touch screen on any smartphone or tablet computer.

Which can be unscrewed to reveal an eraser for when the pencil is used. Of course!
















Update: Another thing this pen can do, apparently, is become useless fairly quickly. The coating on the stylus nub that made it glide smoothly across the screen started peeling off within a week or two of use. Soon enough, the nub started getting stuck when dragging across my phone’s screen, making it difficult to use. In addition, I had trouble getting the mechanical pencil to remain functional. Every other time I tried to use it, normal writing would push the lead back up into the barrel and I’d have to replace it. Alas, the search for my pen continues.
