Glow in the dark white body, black and translucent blue rings.  3d printed in ABS.

Available in 3 sizes: 0.75", 1", and 1.3"

Designed for .355" taper tipped shafts. They'll work with .370" as well, but will need to be reamed out slightly before installation. 

Note: the brightness of the glow in the dark element varies with the level of ambient light.  The photos shown here were taken in total darkness.  Don’t expect these to be super bright the moment the sun goes down.  It’s glow in the dark plastic, not plutonium.
