Tumi Ishi (pronounced Too-me Ee-she) are wood balancing blocks that are are meant to resemble stones. With so many different shapes and sizes, they are fun to hold and stack. These blocks make a great unique gift for that hard to shop for person. These also make beautiful and classy decorative pieces. Put them in a glass dish, stack them on your dining room table, coffee table, or desk and watch people ooh and ahh (and try not to play with them).
