An all-black LAMY Safari fountain pen filled with a mix of water, Platinum carbon black, and inkjet printer ink.
A blank sheet of A4, folded in half three times.
My passport.
A fully loaded Secrid card carrier.
A really nice rock. It has been in my pocket for a year. Don't think about it.
A dumb watch. (Casio W-59. Very small, light as a feather. Green LED-backlight LCD display. 50 metre water resist. Tough, within reason. Effectively infinite battery life.)
A beta of the PinePhone Pro, equipped with dreemurrs archlinux.
A USB drive containing all of my computers' boot partitions and Archiso.
Yeah, I know. Like I told the other guy, it's a stock image. An image of the real pen wouldn't add anything except ink in the window, and I can't take a better picture than whoever did the stock image.
The ink in the window looks entirely unremarkable.
...
/me looks at ink in the window for five minutes with a bright light backlighting the window.
...
Yeah, the ink in there is entirely unremarkable.
It's just grey air bubbles and black water.
IDK, you want a picture of the ink window anyway?
