|To the right we have Spiderpen and it's packaging, to the left is a Pilot pen I found at Walmart.
Note the similar pocket clip, the coloring, size and general shape. Even the end cap is very similar. In fact, even the striations in the plastic bear an extreme resemblence.
Cool, looks like the clip is just what we need.
|You can see that the pen's overall color is a very close match. You can also see the end cap a little better here, wrong color, but otherwise strangely similar.|
|With the pen open, the differences obviously become more apparent, but the overall cap length is about the same, which is good. To make a Spiderpen from this Pilot would definitely require some heavy modification, which hints at some serious engineering in the Spider pen. Though I'm not going into details here, it's really quite clever in ways you can't tell just by looking at a photo.|
Here's the side it's supposed to be on !
