This is our most affordable chess tournament carrying bag. Inside you'll find a zippered compartment for chess pieces, loops to restrain a rollup chess board, and a padded pocket for holding a chess clock. This bag is primarily intended for our single weighted club size plastic chess sets with a 3 3/4" king. Rollup chess boards up to 20" square will fit but you will find it a little tight (not a lot of extra room like our large model). Chess bag measures 20 1/2" x 5 1/2" x 2 1/2".
