These are great for use in commercial kitchens, restaurants, hotels, offices, factories, schools, hospitals, restrooms, and more to provide clear signage for safety. This is a commercial-grade, high quality, and durable plastic sign. It is waterproof, and the writing won't fade even after years of use. This sign measures 24.5"x 11.7" & 12 "wide (when open) and is double-sided with the same message on both sides. It is easy to store and carry, and can be folded for convenient storage when not in use. This is a great addition to your safety precautions.
