New this season from Do-It Molds is the Diner Shiner. In lieu of the traditional collar it uses the wire plastic keeper. The mold has six cavities and make 1/16, 1/8, 3/16, 1/4, 5/16, and 3/8 head sizes. All have the recessed eye pocket. The mold is an easy caster and the sprues break off very cleanly.
Here are some 1/16 and 1/8 ounce heads finished using an airbrush and having 2mm and 2.5mm eyes respective of head size.
