These cute little mushrooms will project rainbows on the walls of your home when hit with direct sunlight. They are made from vinyl and apply with water and static cling they are safe for rentals and are easy to move around as the sun's direction changes. Application instructions are included! Place them on east-facing windows for morning rainbows, west-facing for afternoon and evening rainbows, or south-facing windows for rainbows all day! They are not recommended for north facing windows as they don't receive enough light. The metallic copper colour goes perfectly with any decor - from boho to classic. It's neutral enough to match anything, but beautiful enough to stand out. The decal measures 6 inches tall and 5 inches wide.
