Double DVD cases are a single-piece plastic case with two creases, which folds around and snaps closed. It measures 135 mm x 190 mm x 14 mm. The outside incorporates a thin piece of see-through plastic which can hold a paper wrap. They are the same size as standard DVD cases but have two disc clips rather than one.
The most popular colors are black and clear, but other colors are available. The advantage of using a clear case is you can also print the back of the wrap as it can be seen through the case.
DVD cases also have clips to hold a booklet on the inside of the case, and a whole range of additional booklet options are available.
