Does exactly what it’s meant to do and is easy to understand. The finish is fine, but could feel a bit more premium. Overall, a practical safety sign.

Good basic sign that communicates the risk effectively. Material is decent, though slightly thinner than expected. Still suitable for most indoor applications.
