A small jar that is approximately 3/4" in diameter. And 1-1/2" deep forms the base of this cobalt blue mushroom made of polymer clay. The mushroom top is embellished with glow in the dark dots, spritzed with blue glitter and heavily coated with clear epoxy resin. It screws on and off for access to the jar space inside.
