My company is launching a mini binder product (called the EarthBinder -- They are 100% recycled) that has similar applications. We are offering these in two forms: Companies who want a custom imprint can buy in bulk, and we are also in the process of developing a catalog of titles that will be available for individual (although we may sell them as three or five packs) sale. As the resident photographer in the office, I offered some suggestions for titles. The fact that the pages are removable seems a plus so you can keep the exposure notes with the negatives.
Within the next few months, we'll have our catalog up for sale on-line.
Sorry if this seems excessively solicitous. Seemed relevant to the thread.
