Allow me to introduce you to the Viking...
and the Gladiator, Alien & Skull Thumb Screws
(these are wacky.)
So I guess people buy these for computer cases...I'm not really sure.
But they are all over the internet!
Do an internet search for "Themed Thumb Screws" and you can find where to buy them, like Ebay or Amazon.
I knew my industry had an infinite amount of possibilities...
but now, having themed head styles like these, our market just got a little bigger.
Am I going to have to start stocking these?!
(Maybe the viking - it's my favorite.)
