From the website:
The Sanguinary Priests are the Apothecaries of the Blood Angels, charged with preserving the Chapter’s precious gene-seed. Each Priest carries a blood chalice, each believed to contain a sliver of the essence of Sanguinius himself and which galvanises nearby Blood Angels to even greater feats of heroism.
This 11-piece plastic kit makes a Blood Angels Sanguinary Priest armed with a double-edged chainsword. He holds aloft a blood chalice and is equipped with a narthecium, the instrument of all Space Marine Apothecaries. It also includes a scenic 32mm round base.
