Planet Eclipse ETHA2 / 3 BS Ball Sensor Lightpipe Sticker

The Planet Eclipse Etha2 and Etha3 BS Ball Sensor Lightpipe Sticker isn't a sensor itself but a light-guiding film that makes the built-in breech sensor's status (ball present/absent) visually clear, shining brightly through a small window to confirm the marker detects a paintball in the breech.
