Now let’s talk about the deck! This is a “petit” version, meaning it has 36 cards…but Jean has added 4 “Mystery Cards”. There's an explanation of the mystery cards and ideas of how you can use them in the LWB. The cards are made from heavy card stock and are not sealed so you must never get them wet. Jean also suggests keeping them out of long periods of sunlight and do not use them near flame. This deck will require a little care on your part but I think you will find it well worth it.
