Stiffys are made from an indestructible single piece TR-90 frame with scratch-resistant nylon lenses. It’s a breakthrough in not breaking.
We eliminated the weakest point in the sunglass design, the hinges, and created the world’s simplest, long-living sunglasses that will never break.
No hinges, no teeny tiny baby screws, no breakage. So while other sunglasses are designed to break, Stiffy’s are basically everything-proof.
The average human-lifespan is only 80 years, which isn’t that long. Stiffys come with a double lifetime warranty and a living will and testament so you can pass them down to your next of kin.
Just push the Stiffy’s leash into each end of the frames over the metal pin. Yeah, that’s it. A little thing called axial tension locks them in. To take the leash off, pinch close to the frame and pull until it pops out. Don’t worry, it won’t break. We promise. Here’s a pro tip: if ever the leash starts to wear or slip off the pin, just give the ends a little trim
