High-quality carbon fiber ring liners.  These are already completed with a comfort finish on the inside and ready to use as a liner for the rest of your ring.  The outside of the liner is flat from edge to edge.  Carbon fiber is very light-weight but extremely strong!  Great to pair with a material that needs additional strength like wood or resin.

Choose the width and then the size of 5 different ring liners.  Liners are available in 8mm and 6mm widths.  8mm wide comes in sizes 5-15, 6mm wide comes in sizes 4-12.  You're getting a nice 20% discount by buying the 5 pack!
