I work as a delivery driver for one of the parcel company , handle about 2,000 package a week . these glove do not last three week , and by that time the fingertip have serverd and a nice hole develop at the palm . I can not imaging how they would last in-building where 5,000 piece be handle in one night . surely Ironclad could have develop this glove with feedback and field testing from actual box handler before label they as such .
