The art department at the Academic Bookstore on the Ave stocks small miracles of design. At the moment, they carry two cases for writing instruments that are useful beyond their intended purpose.
One is flexible, synthetic, and rectangular, about an inch and a half by an inch by eight. It makes a good case for glasses or the elements of the hiker's ten essentials.
The other is a cylinder of supple vinyl about the same size as the first. I carry grooming essentials in one and attach a keychain with flashlight. The case makes it easy to fish keys out of the depths of my side bag.
