A card tray that fits standard sized cards up to 92 mm. 6 trays fits into a standard board game box. Note that the outer dimensions of a standard box might be consistent but the inner may not. The inner dimensions of a standard game box vary slightly due to the thickness of the cardboard board. This is designed for a Dominion card box which is average in thickness.
