An Off-Zel vase is a very rare piece of pottery. It was produced by Mark Off-Zel, who was an artist from Sirrie IV. He died sometime before 2366.
Kivas Fajo had one of the few remaining vases in his collection. (TNG: "The Most Toys")
K'mpec kept a similar statue in his quarters aboard his Vor'cha-class attack cruiser in 2367. (TNG: "Reunion")
