Acrylic is known for its impact resistance (17 times stronger than ordinary glass), but it is still possible for it to be damaged if it is subject to excessive impact or dropped onto a hard surface.
If your acrylic product becomes damaged, please dispose of it carefully. It is designed to shatter into larger pieces than glass, but it can still have sharp edges.
The surface of acrylic can become scratched over time. This can be reduced by gentle cleaning (see above) and by storing carefully.
