Help with materials

Ive read multiple post. Im currently working with 110lbs cardstock. I laser print and cut with cricut. Spray glue and clear coat. Cards work fine and people like. Box looks fine but feels cheap. I know of the websites but its not cost effective for me at the moment. Looking for help with boxes and if anyone has ideas for cards. Its a 30 card deck domino size (1.75x3.5”). Need cards to hold up multiple shuffles and box to be decent quality.
