As these game will be used for parties and perhaps involving alcohol, the cards life expectancy won't last long. I sleeved mine and used Mayday Games 63.5mm x 88mm sleeves(NOT PREMIUM or they won't fit into the box including the expansion).
Could you post a picture and show us how it looks like in the box with the Mayday non-premium sleeves? And additional pictures if you would like.
Thanks in advance!
