Blind Sides are the perfect solution to blocking out that pesky sliver of light from the sides of your blinds & curtains to ensure complete darkness in your nursery/bedroom. Their easy-to-use design come in pairs & simply hooks over your existing blinds or curtains & can be adjusted to fit your exact window height. Blindsides are lightweight & portable & be rolled up & taken anywhere you go including on holiday or when staying with friends or family. They are ideal to be used in your baby or childs nursery or bedroom but can be used by people of all ages who prefer a completely dark room for a good nights sleep.
