Colorful, fun and reusable gel gem are a dynamic new way to express yourself and decorate your surroundings. Flowers, fish, stars and dozens of other shapes can stick to your windows, mirrors, computer monitors or drinking glasses - any non-porous surfaces. Done stick gel gem is on drywall, wood, painted surfaces, plastic, fabric or other porous surfaces, and they will leave oily marks. Sends a message to your neighbors, adds a splash of color, or creates a detailed mosaic. Then, when you feel the creative itch again, take down your design and start again.
