or so i must tell myself

I am prepared to accept that others may have a lovely black sharpie like the one I have for packing. I know others must have a tape gun for efficient box-taping. But does anyone else have THIS?:

That is, a tape gun with built-in pen storage, MADE OF TAPE? I think not. Note the pen's angle of repose, so it neither falls out nor interferes with taping. It is something that could have been conceived by only one mind.
