No personalizations so you can have it engraved (we don't do the engraving) with a child's name. This is an older model so not likely to find another one like it . Measures 1.125 inches long by .75 inches at widest point. Thin - about 1 mm thick. Perfect for a necklace! Bring your own necklace to the jewelry party. Marked PdO (presumably the maker) and "Ster" (for sterling) on one side. Weighs 2.3g. Will ship USPS with tracking free to winning buyer.
