This is a vinyl wall decal of the Shield Knot, a symbol of protection against evil forces. The interlocking shape also represents infinity, & the four corners, the four elements. This is an ancient universal symbol, used by the Norse, Celtic, & Mesopotamian cultures, & also used in Christianity & the Kabbalah. This version is traditionally a Norse symbol. Great decor for the Celtic, Asatru or Norse home! Great gift for fans of the Vikings or Norse mythology. Made of high quality matte vinyl, this decal will adhere to your flat painted walls, furniture, laptops, or any flat, smooth surface. I have several sizes available, the size can also be customized. The decal pictured on the wall measures approximately 11 x 11 (photos are not exactly to scale). These are removable, but not reusable once they are removed. It comes with instructions on how to install. These decals are made for indoor use, they are easily removable for at least 2 years, & will last indefinitely indoors. I also have high quality outdoor car decals which will last for at least 5-7 years on your car.
