Google tells me that Japanese Rice Bags are traditional pouches used in Japan to carry rice offerings to the temple during religious ceremonies, or to hold gifts destined for a close friend or relative. I think the bags are a gift in themselves.  I use mine to store my collection of zippers and snaps, hold plant pots (the not so nice ones), fabric scraps, treasured letters.  So nice when something so pretty is also useful. They are made from upcycled upholstery fabric samples so no two are the same.
