Barnacle Button, Pewter, Smaller Size 1/2" Shank Back, from Green Girl Studios USA #G340
Lead Free Pewter, USA made by Green Girl Studios. Like all Green Girl pewter, these are excellent quality, hand made, dimensional, detailed. Theses are mostly black with shiny silver color coming through on the higher areas of the barnacles. Shank hole is about 2.75mm. Shape is irregular, vaguely oval. We love these.
