These are handmade D20 pins with the #20 side centered on the pendant.
Pendant comes on black cord chain (18" long with a 2" Extender & lobster clasp) or 18" silver tone nickel free chain with barrel twist clasp. If you see it comes on a chain and you want it on a cord instead (or a chain instead of a cord) just note that in the purchase notes. IF YOU DO NOT NOTE THIS IT WILL COME ON THE CHAIN/CORD IT IS PHOTOGRAPHED ON.
Necklace also comes with a single color for inking in numbers BUT ONLY IF YOU NOTE A COLOR AT CHECKOUT. IF YOU DON'T, IT WILL COME AS SHOWN.
These shift an array of colors in the light. They also lay flat because they are only half a d20! Yay!
