Continuing the trend of making big bucks with simple ideas, the Ask the Octopus iPhone app, the Snuggie, we bring you the Antenn-aid. It may have started as a joke idea between two designers from Brooklyn but in less than two weeks it’s become a thriving business. A simple bandaid design that covers the death spot of the iPhone 4, Szymon Weglarski and Jon Dorfman opened up shop on Etsy in July 16 and since then, they’ve made close to 2,000 sales. Initially, the Antenn-aids were sold individually but with such high demand, it soon proved to be inefficient, so they switched to a six-pack of assorted colors, which costs $5 plus shipping. Their tagline? “Apple made a boo-boo. Make it all better.” Technical specifications? “Umm.. it’s a sticker.” It just doesn’t get much simpler than that. Now if only we had thought of it first.
