Small Cremation Urn “ Pewter Lillies Infant Urn” Cold Cast Polystone And Pewter. Beautiful, heavy urn. I bought it in an online auction , being sold as a lidded bowl. The pewter vined lillie’s are a work of art. It has a couple small scratches (see pics) but otherwise great condition. Could be used for pet ashes also , it holds up to 70 cubic inches. It does NOT have a screw on top , it would have to be glued. It has a felt bottom .
