These pants were great, fit as expected.  As a bonus gift, I was sent the following object in the pocket.  It is 1.5x1.5x. 5 in.  Does anyone know what this is?

Revision:  After one month of wear, the crotch shredded to the point that they were not even worthy of being donated to good will.  Due to the presence of other people's stuff in the pockets, and the abnormally short life of these pants while in my possession, can I assume that these were recycled pants from a previous return that were sold to me as new?

The lack of durability has caused me to drop the rating from 4 (thanks for the pocket present) to a 1.
