Nice frames. Not so much customer service.
I really like the frames. They are nice wood and quality glass. My only complaint is that I ordered 3 in walnut to go side by side on the wall over the couch. I received them one by one and the last one that came was not walnut finish. I was easily able to request a return of the last one but when I reached out to ask them if more frames would become available in walnut again, I got no response. As I needed 3 matching frames, I wasn’t sure what to do. I checked daily on Amazon to see if they were in stock and luckily they did come available about a week later. I ordered and received the last frame in walnut and all is good. But, it would have been nice to receive a reply from the company.

Quality Frame
Beautiful frame, well made, very secure backing and easy to hang as brackets are pre-mounted on frame, was provided hook & nails too! Will buy more!
