Lightweight and shatter-resistant, our mirror plastic sheet set offers a reflective surface and more safety than a standard glass mirror. The 3mm acrylic safety mirror sheet can be easily mounted onto flat surfaces and ships with a plastic film for protection during transportation. Use the plastic mirror set in a home, office, school, or bathroom. Each mirror sheet measures 11 x 8.5 inches. Not only great for adults, but this mirrored acrylic sheet set is also ideal for children and even animals such as birds or horses!
