The internal dimensions are approximately 13.1cm x 7.5cm x 3.8cm. It easily holds my boxed Medieval Tarot deck and will also hold most larger decks, although they would probably need to be unboxed. For the price, the quality appears to be very good; the eBay listing describes it as being made from "hard resin". I wanted something a little different that didn't have an obvious theme to it; for example, some of the skull boxes I've seen are quite nice, but wouldn't be appropriate for most of my Tarot decks. I'm really fond of the green man and tree of life design on the box and especially like the fact that it has been artificially aged. It looks much better in real life; the photos do not do it justice.
Hope that helps.
