A gorgeous slab of East Indian Walnut wood with beautiful grains. This model is distinguished by the pockets being slightly deeper and the clasp to hold the box closed being via magnets rather than a string and post. It also has special marbles with a grainy outer texture which give them a good feel when playing. When opened it is 20" long. This set is of a quality that you will be pleased to own or give as a gift. Weighs about 2 pounds and measures 2 1/8" thick when closed.
