Hasbro Fantastic Crystal Creations lets you create unique, sparkling gel designs. Thanks to the included interchangeable design shapes (12 pieces) you can bring your imagination to life. Fill your chosen shape with gel from the 4 included bottles (each with different color) and watch it spin. Once satisfied with the design, seal the center hole with a provided sticker and let it dry. You can display your creations on the provided stand, hang them on a window using suction cups, or wear them as a necklace. The device also features a built-in storage area for the gel bottles and caps.
