Trio is probably the most bidder-friendly Bidding Box. At the World Championship Zia Mahmood exclaimed: "This is the best box around, it makes the bidding easy!"

​

Trio is also very easy to handle between sessions as it can be opened/closed without re-arranging the bidding cards. It can also be fitted to the side of the table using adapter sets. 

​

Choose between red, green or blue with English, French or German bidding cards.
