I agree with you, plastic/bridge/jumbo/4-colour would be AWESOME, however, some of my players (most) dont like it and it throws them off.
I also believe that the bridge size do not exsist, I have plastic/Poker/ ? / 4 color..
I've looked and looked and only found the following:
Copag plastic 4-colour jumbo poker
Faded Spare plastic 4-colour jumbo poker
Vision4Color plastic weird poker
