Nice Sign

It stands out well. Good thick material and design modified from my input. It was strange that UPS lost the package in Seattle for lack of address when the address was correct and it matched the address on my UPS account. Alls well, I finally got it.
SmartSign: Sorry for the inconvenience. We’re sorry to hear about the hiccup with UPS, but we’re happy it reached you safely in the end. We truly appreciate your patience and support!
