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 in a rich monochrome spectrum. & because i-Type cameras have their own rechargeable batteries we dont have to put one in the film meaning you save money on every single pack. Just remember it wont work with 600 cameras no matter how much you want it to.
