Traditional lens cases are bulky and a "one-size-only" solution. Well, WANDRD's engineers (who may or may not have been recruited by NASA) have created a space-saving and protective solution that will fit just about any size of lens you carry. You'll never want to travel without the Inflatable Lens Case again. And no, they weren't recruited by NASA. But only because they already work at the most remarkable organization in the solar system.
