Normally I would not want to do anything to compromise an LEs color (in this case, a shimmery pearlescent white), but today I went ahead and converted my Iridescent Pearl Kaweco Sport to an eyedropper fill.
Why did I decide to do this? What color did I fill it with? The body of the pen is not 100% opaque, so it does matter.

These are the kinds of questions best answered in a vlog / youtube video.
