👍🏿Better than others:

🖒a, The case's are made with quality. Easy open and take out steelbook to watch the movie. others you may need to get them open without either jamming my finger deep and ruining the case for good or wasting 5-10 minutes trying to carefully re open it.
🖒b, Clear acrylic, super quality, won't get yellow and brittle. Other plastic cases are too stiff, won't folding,
🖒c, Acrylic material was taught enough, won't like other plastic box when folding into the box it never looks good it bulges and the top and bottom flap don't stay flat causing the steelbook to get stuck and therefore won't close!
🖒d, No need to push-lock tabs on both bottom, other plastics has to push-lock tabs, it was difficulty to put together, and need to fold the flaps both ways when you're getting them ready or you'll end up with one of the flaps folded inwards, which will prevent your Blu-Ray from going all the way in.
