You are buying a lot of 10 bags.

These are listed as 8" x 8" on original packaging (bulk package).  They are actually closer to 7.5" x 7.5"

They are thin cloth and are made in India.

See pictures to get an idea of size.   

These are genuine Coach dust bags.  They were meant to be given away as freebies, in a retail location, with purchase of any small Coach item.
