I wouldn't worry about the generic looking card boxes, these look just like the boxes that were used to ship to cardrooms/casinos. The only ones I've ever seen come in the clear cases were those sold to the retail market (cardrooms don't care that much about the card brand package marketing). Search for the threads with the Grand Victoria casino cards that were sold some time back. I remember mine came in the generic green boxes. And
@Tommy sold quite a few Gemaco setups in the past and I remember those all came in the generic card boxes.
However I would recommend that you contact them immediately about the missing/unfulfilled setup. One of the things Kardwell has been know for in the past is bait & switching of product they don't really have in stock. Also their communication was horrible, getting them to refund money use to be a real chore. I would stay on top of them about either getting a refund or fulfilling the order they sold you. Hopefully Kardwell is turning things around with support.
Glad you got some to try, the Superflex cards are much better than the GemPro for sure.
