This is a mobius strip of Level 1 or Super Mario Bros. The whole level is wrapped around itself in a single surface, and poor Mario begins and ends at the same spot every time :(

All the elements from the level are there: every mushroom, turtle, cloud and star. They are all carved out of the surface at different heights, which looks fantastic when you have a light coming from the side, and each block casts a shadow.

It's a great piece to have on your desk, or to hang from a string to let it spin around.

Pen not included. This sleeve is for Kickstarter backers of the Pen Type-A campaign. If you bought a USA made version of the pen at shop.cwandt.com, it'll fit, but it will not be a snug fit. These sleeves sometimes comes with some extra powder in it, please make sure you get it all out. Video of powder removal -> https://vimeo.com/47323037

When is the last time there has been an innovation in buttons? Answer, just now! This button not only holds your shirt together, but it also holds the cord for your ear buds and helps to keep them in your ears. Works for apple ear buds, and any cords with a 2 mm diameter.
