I'm giving these 5 stars because the price is pretty great for what you get.
These inexpensive frames are perfect for certain things. Our college art club uses them for art presentations and art competitions. We can afford these on our limited club budget and they look fine.
They're easy to use, even though I know that some customers have complained that it is hard to get the glass out of the frame. There is a little lip on the plastic frame edge that you have to pull back to get the glass to separate from the frame. The glass pops out from the front. I've never had any trouble. Just take your time - don't be rough with them.
There's nothing special about these frames. It is a plain black plastic that is barely visible. If you want to actually see the frame, then you probably won't like these. If you don't want a frame that looks like plain black plastic, then you probably won't like these frames.
On the 8.5 x 11" size of this brand, the glass is quite thin. Again, be careful. We also purchased a handful of the 10 x 13" size and the glass is thicker. I didn't feel like I had to be quite as gentle when separating glass from the larger frames.
I've purchased dozens of these over a few years time frame and have always been satisfied. These are a great buy if you aren't picky!
