Sometimes I leave colors out when I'm making a rainbow. Sometimes I add one color in quantities not found in yer standard every day rainbow. And you know what, I'm cool with that. Made with resin and ink, the piece is about 6 inches in diameter and 1 inch thick. She comes with her own display stand. If you prefer to hang the piece on the wall, also included is a reusable sticky tab. Shipping fast and free in the USA, $10 for international shipping.
