Carat Case X3

The magnetic closure is firm enough that I don't worry about it popping open in my bag, yet it's easy to flip one-handed when I need a deck. Fits three standard decks snugly without any rattling around.

I was worried three decks would make the case bulky, but it holds them snug without any extra wiggle room. The window on the front shows off the card backs nicely, and it’s sturdy enough for tossing in my backpack.

The magnetic closure snaps shut so satisfyingly and the interior is snug enough that my Thirdway decks don’t slide around at all. I’ve been keeping my three favorites in it daily and the clear window makes it easy to grab the right one.
