Received my decks on Monday. Was able to crack open the envelope on Tuesday, then dig into the box. The slip cases are very stout. I really am impressed with them that far, haven't popped one open yet. I don't pop a deck until it's on the poker table. I think maybe one deck for new years, the other saved for some time after. Also received my deck jackets on Monday and was able to crack that box on Tuesday as well. No damage to the deck jackets even though it looked like they were tossed in all willy nilly, packaged in a hurry and kicked out the door lol. The box was good high quality protection.
