I've embedded terahertz into resin. There's one terahertz piece and two fluorite pieces inside the shaker. It's star-shaped, with purple and pink colors, and contains terahertz and glitter. It comes with a gold heart-shaped lobster clasp. [Size] Approximately 4cm [Materials] Terahertz, fluorite natural stone, resin, beads, glitter, metal Although unused, this is a handmade item, so please refrain from purchasing if you are looking for perfection. Thank you.
