Luxury goods like watches and pens have already capitalized on this (Fisher Space Pen, Omega Moonwatch). I could see other high margin luxury brands snagging a seat:
- Sneakers (Air Jordans -> Space Jordans?)
- Jewelry (Diamond industry could play up a diamonds/stars theme)
- Fashion (play up the weightless/effortless aspect)
Any brand could get in on it if someone figured out the economics of a testing service. Small brands and Kickstarter projects could pool resources and fly up a few hundred toys and say they were 'tested in space'.
