I am a big fan of the frames that have two panes of glass (so no matting). Went to my go to store for these. "They've" changed the design. For some reason, you have to pry apart the backer posts which are pinned in. Absolutely ridiculous. Problem was that I couldn't line them back up. I looked at previous frames and saw these little things attached, so looked and found. If you're asking yourself why I didn't take rather back...it's a bit of a drive to get to major stores.
