I-type film is a new generation of instant film, optimized for I-type cameras like the one step 2. That means you get the best photos possible with your one step 2, as crisp, clear and colorful as every photo should be. And because I-type cameras have their own rechargeable batteries, we don't have to put one in the film, meaning you save money on every single pack. But don't try using it in a 600 camera - it won't work, no matter how nicely you ask it to.
