Blu-ray Case Mailer. 7 x 5-3/8 x 5/8". White-one-side E-flute corrugated cardboard.

Reasonable performance

Good product but I thought the cardboard would be thicker. When I mail a SteelBook or something more valuable, I always feel like I have to use another product, or put these in another case... which kind of defeats the point.Perhaps there could be a thicker cardboard option that is a little more expensive? ANSWER: Great news - we are currently working on a new mailer for SteelBooks. Stay tuned.
