This product exceeded our expectations. We ordered the HIP version of these in the .080ga blanks. The only thing I would recommend is that they put a picture of how the HIP and Diamond versions look on all their items. Thank you Hall Signs for your awesome products.
These engineer grade reflective blanks have been of good quality for us to use in our shop.
