This is a lot of three (3) arrowheads or projectile points. They are styled after neolithic points, but these are modern reproductions. They have had the "Aqua Aura" type of treatment in a vacuum chamber to give them this coloful iridescent look to them. They are really pretty in hand and the colors change as you or the light moves. I'm not sure if these would be practical to use as actual projectile points, but they would make great pendants, keychains, or curios.
You get all three arrowheads shown. They measure a little longer than one inch each. I'm not sure what type of stone is under the treatment, but it feels like typical flint.
Refer to the photos. The black centimeter cube and steel ruler are shown for scale and are not included. You get all of the arrowheads shown.
