Here is the bag of coffee beans I received. There is no material listed, but I believe it is a burlap bag. I understand it was designed for the Japanese market. The design, featuring traditional Japanese clothing, is very impressive. Size: Approximately 89 x 52 cm. Please allow for some margin of error. Please be aware that there are some frays, uneven coloring of the fibers, and markings in red pen. Please consider these points before making a purchase.
