Bag of 15 factory new NORMA unprimed 45-120 Sharps brass rifle cases. (45-3 1/4”)
Odd numbers of cartridge cases is the result of bulk bagging. Bulk brass is sold in barrels, generally by weight and it is not uncommon for odd number of pieces remain.
Brass case mouths MAY not be perfectly round from the manufacturing process, this can be corrected by running brass through the size die (always recommended) prior to loading
