We used this surface for playing mahjong until we replaced it with a junk mat. It comfortably fits small two player games, when fully opened, the playing area is 47.5cm x 47cm, not counting the lip (extra 1.5cm). It opens up and contains a shallow insert that can hold tokens, poker chips & cards (we'd recommend keeping those in bags, not loose though). It's not heavy and contains a handle like a briefcase so it can be carried places easily. Please ask if you would like more pictures. Will ship the next working day :)
