Premium Super Thin Viscosity CA glue. Each bottle contains 1 oz of super glue. CA Glue is the main product we use to add inlay material to Glowstone rings. Super Thin Viscosity is helpful when you are trying to thoroughly saturate all inlay materials, especially with color pigments. If you are getting dry spots with Medium, Super Thin might be a good way to go! See our YouTube channel for instructions and insight!
