The Chessex counter tray can hold up to 800+ 5/8"" counters and is designed to fit into nearly all games including the old Avalon Hill Bookshelf game boxes. The lid is attached to the tray and will open up and lie flat. Five contact points help assure the lid to stay closed even if dropped. The specially designed 16 angled compartments add to the ease of counter removal. The compartments are shallow enough so the counters will not flip when moved. The trays nest for more compact stackability. Three trays stacked measure 1 5/8""tall.
