I didn't count to determine that I received 100 washers, but it is in the ball park - no complaint.  However, the washers were all lumped into a single package, requiring me to sort them.  On top of that, they all seem to have the same inner diameter, although different outer diameters.  I needed something on the order of a 1/4" or 5/16" inner diameter, but they are all much smaller.  The manufacturer should (1) sort them, and (2) let the buyer know what the inner diameter is.
