The white porcelain insert presented is designed for an octagonal soap box, probably a transferware item. Unfortunately we do not have it to offer. The draining insert measures just shy of 5 inches long by 3 1/2 inches wide it is 1 1/2 inches deep. This item is porcelain rather than ironstone. It shows some use rubbing on the corners. The rim also has one tiny glazed-over chiplet, done in the making.
