Nape piercing
Somewhat less common are surface anchors, commonly made from surgical implant-grade titanium. A surface anchor has two parts: a base or foot which is inserted under the dermis during the piercing process and which incorporates a stem exposed to the surface, and a decorative disc or ball of jewelry which typically appears flush with the surface of the skin. Surface anchor nape piercings are most commonly found placed symmetrically on either side of the spine at the nape.
Anchor Stone Blocks
The new factory manufactures and sells all 15 of the sets in the main series (GK-NF) of Anchor sets as well as some sets modelling the Michaelis Basilika in Hildesheim and the Brandenburg Gate. They are widely available in Germany, including in the KaDeWe department store in Berlin, and are readily available online. A new series of sets for younger children called "Die neue Steinzeit" ("the new Stone Age") was introduced in 2012. The sets tend to be expensive, but high-quality; antique sets are just as playable now as when they were originally produced. Sets being produced today are made to the same specifications as the antique ones, so they can be easily integrated. In addition to construction sets, the artificial stone formula has been used to produce simple flat puzzles, such as tangrams.
