7 Pipe agrees with Apple's design mantra: think of cool products, and let the engineers figure out how to make them. When we dreamt up a lighter pipe with glass inside, we were not sure it was possible. In fact, some thought it was impossible. A year and a half of R&D later, we finally had a working prototype. Time moves fast, and we are already on our second generation of the 7Pipe, called the 7Pipe Pro. Please read on to see how we improved an already revolutionary product.
