Ring Fob for a Ball Chain

This is a ring that can attach to ball chains, which you typically find on dog tags, pull chains for ceiling fans, and closet lights.
I took the top part of ICEPICKTONY's design, the part that holds the ball chain, shortened it from holding 4 balls to only 2, and attached it to a ring I designed.
The groove in mine, for me, is to hold a band of glow-in-the-dark paint, but I suppose it's stylish too. The ring is 2 inches across, and about 1/4 in wide.
I then designed a smaller one that had grooves in the sides as well, for maximum glowage! It is 1.5 inches across.
