My family often plays games like 3-13, which requires several decks of cards. If we use the low-profile card trays, we have to frequently add more cards each time, or the whole deck might scatter all over the place if we're not careful, which is really frustrating. After trying several ready-made solutions on the market that weren't satisfactory, I decided to design one myself.

This tray is of standard size and is often used in card games such as Canasta, but its overall height is slightly higher. Users can further enlarge the tray size according to their printing needs, or even create a higher version of a customized design.

Update! A new three-card card holder has been added. To create it, just stack two double-card card holders together and offset one of them horizontally by 83 mm.
