Both have the same 310gsm linen cardstock, as the latter is the mother company of the former. Anino Lenormand comes in Poker and Mini sizes while The Gravenchase Lenormand comes in Bridge and Mini sizes.
Both also come with a free zodiac oracle done in the style of each deck.
Here’s a tip too: if you’re just getting the poker/bridge-sized versions of the deck, I recommend getting them at my Make Playing Cards store since those versions come in hinged clear plastic cases – if you are into those; while the minis there as well as all the decks (Poker-sized, Bridge-sized, Mini-sized), in Printer Studio come in white boxes with a clear plastic window. My Printer Studio store also has zip pouches with designs that go with both decks.
