  • 2-year warranty on every illuminated sign
FAQ

Questions buyers ask us.

How is the diamond effect made?

Each hole is cut with a faceted bevel, not a straight punch, so light reflects off the angles. A premium technique with an unmistakable result.

Is it visible in daylight?

The faceted metal catches sun even when off; at night with LEDs on, it is spectacular.

Is it pricier than standard perforated?

About 40% more due to precision faceting — a choice for premium brands wanting something distinctive.
