Hello MeZilch!!! Whoa crazy small world the internet is, init? I actually got the idea to order the pen from your video a little while ago. Had to have it for it's small size, telescopic feature AND because it holds a Fisher Space Pen refill! Love your video's btw, and insta subscribed! My pen is simply held onto the keychain via a small keyring loop slide over the pocket clip and mildy clipped into place at the top. Admittedly not the most secure way to fasten the pen to the keychain clip, but works well enough for now. I'm actually thinking of taking the pen into a jeweler to see if they could drill a small hole into the top of the pens pocket clip, that way I could fasten the small keychain ring through the hole to secure the clip onto the pen better. Again, XXL ups for the great videos, much gratitude! And very nice to meet you.
