Sharan pinhole cameras are Japanese-made cardboard camera kits that you buy and build yourself. All the parts are pre-cut, and can be assembled using tape in about 1 to 2 hours with the help of step-by-step instructions. The STD35 is a standard 35mm pinhole camera, while the Wide-35 allows you to take panoramic photos.
Here are a couple sample shots with the STD35:
