"Sprockedermis" the gear skull doesn't don skin like you and me. The wonder of anatomy and engineering is, instead, shrouded in hundreds of weathered bronze-colored gears, screws and other tiny machine components. Even his teeth are a bit unusual, to put it lightly. While perfectly aligned and cavity-free, the peculiar rows of chompers are comprised of only nuts and bolts! Despite his odd complexion, Sprockedermis' avant garde sense of anatomical style is perfect for display, especially for steampunks, Victorian sci fi fans, modern machinists or anyone who appreciates quirky home decor. Spockedermis' metal fastener "skin" is secured carefully in the tough cold cast resin material that makes up the underlying skull sculpture. You may lose plenty of nuts and bolts in your garage or workshop, but you won't lose any from Sprockedermis! At around 4 3/4" tall x 4" wide x 5 1/2" deep, he's ideally sized for desktops, countertops, bookshelves, curio cases, end tables, bedside tables and countless other locales. But regardless of where you showcase the quirky-chic skull sculpture we affectionately call "Sprockedermis," he's sure to draw attention and spark lively conversation!
