Good to know

Store the film flat and protect it from sharp objects to maintain its optical properties. Always inspect the film for pinholes or scratches before each use, and never look at the Sun through an unfiltered optical instrument. The film is not pre-mounted; you will need to construct a filter cell or holder according to your equipment's specifications.
