This Graduation Hat Card box is perfect for sitting on your main graduation party table for all your guests to stuff with cards! The box will accept cards up to 5"x7" with envelopes the lid lifts easily if larger cards need to be placed in diagonally. The box comes sized at approximately 7" x 8" x 8" with the lid in place and it is compatible with both the 8x12 and 12x12 mats.
