These rings are perfect for coordinating any outfit or showing pride in team colors. Go red and green for Christmas or neon for some extra pop! Thin stripes, thick striped or one solid block of color. Whatever fits your mood of the moment. Change the colors cheaply, I like to use embroidery thread $0.39 a spool (not included). The design allows you to keep the thread confined to the top of the ring while the underside groove provides a space to poke the unsightly and uncomfortable knot leaving you a clean smooth finish.
This rings hole is 16mm but email me for more sizes.
