Vintage Miniature Tea Set

Vintage miniature porcelain teddy bear tea set from Japan marked in red. These were from Shackman, Inc., but the box was in terrible condition, and appears to have disappeared. The box was marked 1982, but the dishes appear older. Set includes teapot (with lid), sugar dish (with lid), creamer, 2 cups and 2 plates. There is no actual damage to the set, however, there are many manufacturing flaws (dark fired-in spots and 2 rough areas on the plates which have been glazed over). I need your zip for postage calculation.
