My skull goblets are a mixture of newly cast resin skulls and often vintage upcycled lead free pewter cups and stands. The cups are not removable, they have been sealed in with food safe silicone.
Variations of paint color, pewter patinas, and hand fittings make each goblet unique. Custom requests (or my own desires) have lead the way to crackled paint finishes, extra skull dent/dings/cracks, increases in "charring" and aging, and even to the realm of vampiric cups.
My skull goblets are done as small production runs, usually 2 to 8 at a time. Many stages must be completed outside due to ventilation requirements so production is highly dependant on the weather matching my crafting times. I live north of Atlanta, Georgia, USA and the memes about the weather are pretty accurate. (Entering spring which means The Pollening. There is pollen EVERYWHERE and spraypainting is risky.)
The only website I sell my skull goblets through is Etsy. If you have seen my images selling on any other site they are likely a scam page.
