This is what happens when you don't drug test your factory workers. Shear plastic anarchy. These are Mixed Parts Ultrus Bogs from Skinner and I feel that I am too OCD to own one. I would have to buy them all then rearrange them until they all matched, which would completely defeat the purpose. No one said I was any fun.
If you have the will power not to try and solve these guys like Rubik's Cubes, then you should buy one tomorrow, December 19th, for $170 from his store http://the-art-of-skinner.myshopify.com/. He also has lots of other stuff that your mom would love for Christmas. She told me so herself.
