I've used them to replace a lot of CDs I've ordered that came in the mail with broken boxes and they work great! They are the same as a standard CD case. Luckily none of them were damaged and they were packaged in a box marked "Fragile" and wrapped in bubble wrap. The black section slides out easily to insert album art, and there's room for text on the front as well. They seem to open and close fairly well and are strong enough to serve their purpose.
