These smooth, soft corners are flexible and they're molded with an inward bow to keep them on. They look great and take up less room because they're only about a millimeter thick. Definitely a nice look - the quality of your framing is revealed rather than covered so the buyer sees more of your good work and less packaging. Incidentally, they're recyclable.
