SanDisk Extreme III memory cards are primarily used by professional photographers and videographers who require high-performance flash memory storage for new high-end digital cameras. They are designed to handle extreme conditions, including extreme temperatures and rugged environments, making them suitable for use in harsh conditions. The cards are also weather and temperature-proof, allowing for the recording and playback of 4D Ultra HD and full HD videos with ease. The SanDisk Extreme III cards are optimized for faster app launching and are built to withstand the rigors of professional photography and videography. 

This set of 3 included 2GB, 8 GB, and a 16 GB memory card in a protective storage case.  

Note:  There is data on all three cards from the previous owner.  I do not have the technology to access the data and remove it.  The previous owner took great care of his technology so there is no worry about functionality.
