Kodak 16mm Film EXR 50D 7245 Total 13 Rolls

This was a gift from a friend. I'm not very knowledgeable about this item myself, so please judge from the images.
Volume 1 was opened for confirmation and will be included as a bonus.
This is a set of 13 volumes in total: 12 unopened volumes + 1 bonus volume.
Incidentally, my friend's father stored them in a refrigerator. They are currently stored in a dehumidified cabinet.

Although the items are new and unopened, they have been stored for a long time. Therefore, I cannot take any responsibility for any malfunctions during use, and this is being sold as a junk item. No returns or refunds will be accepted, so please consider carefully before purchasing.
