I really dislike Mofi's mini-LP packagig. Mainly because it's difficult to avoid shelf wear on the cardboard, and it's not replacable like a jewel case. The Art Pepper disc in question is nice since it's individually numbered in gold lettering.
Space isn't really an issue for me, so I prefer jewel or even better super jewel cases. The old DCC/MFSL lift lock cases are still my favorite (smooth top).
