A set of Detective cufflinks made in Shapeways sterling silver or stainless steel. The 3-D printing process can leave small visible printing lines. While I for one really like the unique appearence of the print lines, these can easily be polished out as seen in this forum post from another member.

Items ordered in silver glossy receive additional manual polising from shapeways which should greatly reduce or eliminate any print lines. Shapeways also includes a velvet bag with all silver items.
