I got tired of stumbling my way through my off-grid cabin on the way to pee at night, avoiding turning on the lights as it would wake others up. I'm sticking these glow-in-the-dark doorway markers around so that hopefully I can avoid stubbing my toes on the dining room chairs.

One of my earliest designs. Fits a very popular brand name set.

I promptly broke my strainer so I made this one. Seems to work well. Fits numerous brands.
