The box are made of high quality ABS engineering plastic from Taiwan and the cards are printed on one kind of Indonesia imported pulp, which is none toxic and being an environmentally friendly product, 100% recycle. When closed, the boxes are flat and easy to stack for storing and transporting.

Bidding boxes prevent any bidding errors/misunderstandings by giving a visual reminder of the previous bids and they keep noise to a minimum.The box is only 6x3x1 inch in dimension. The cards can be compactly stored in the box when not in use and the box can be closed tightly.They are suitable for playing at home, club games and tournaments. Great features at a great price! I even offer free shipping.

These boxes are so easy to use. A super design in not having to remove the cards for use and storag, they simply fall back into the box intact. And placing the "Stop & Alert" cards to the rear of the box is so sensible.
