Acrylic Plexiglass Car Show Mirrors 23.5 x 12 x 4 (1/8 Thick/Clear). Includes 2 pieces. These mirrors are made from a high quality acrylic material and are a great alternative from using glass, but with the same reflection as glass. The big advantage is that they will not crack easily from bumping each other on your display and they are a lot lighter to carry around at car shows than glass. They are very heat resistant and durable. For best results do not peel the brown paper off the back as it will help protect the mirror finish over time. Remove protective white film on the top when you are ready to use the product.
