Narrative:

Prior to departure; the FAA started inspecting our aircraft. The captain went outside and spoke to them. Upon returning to the flight deck; he informed me that jack pads were still on our aircraft. The aircraft had been ferried from ZZZ1. After the aircraft arrived; we walked out to it and began getting ready for departure. I performed a preflight. Since it was not the first flight of the day; I did not do such things as open the gear doors. I made sure that the aircraft was in airworthy condition and returned to the flight deck. I performed 4 more pre-/postflts before the jack pads were brought to my attention. There were no 'remove before flight' tags on them. Without the tags; the jack pads looked like any other domed metal piece on the aircraft. I know that if the jack pads had the 'remove before flight' tags on them; as they were supposed to; we would have definitely spotted them. Supplemental information from acn 780224: the aircraft had just come out of weighing when it was returned to the line. A jack pad was left attached to the aircraft which was not discovered by maintenance; ground; or the flight crew on the pre- or postflt.

THE ACFT HAD BEEN FERRIED FROM ZZZ1. AFTER THE ACFT ARRIVED; WE WALKED OUT TO IT AND BEGAN GETTING READY FOR DEP. I PERFORMED A PREFLT. SINCE IT WAS NOT THE FIRST FLT OF THE DAY; I DID NOT DO SUCH THINGS AS OPEN THE GEAR DOORS. I MADE SURE THAT THE ACFT WAS IN AIRWORTHY CONDITION AND RETURNED TO THE FLT DECK. I PERFORMED 4 MORE PRE-/POSTFLTS BEFORE THE JACK PADS WERE BROUGHT TO MY ATTN. THERE WERE NO 'REMOVE BEFORE FLT' TAGS ON THEM. WITHOUT THE TAGS; THE JACK PADS LOOKED LIKE ANY OTHER DOMED METAL PIECE ON THE ACFT. I KNOW THAT IF THE JACK PADS HAD THE 'REMOVE BEFORE FLT' TAGS ON THEM; AS THEY WERE SUPPOSED TO; WE WOULD HAVE DEFINITELY SPOTTED THEM. SUPPLEMENTAL INFO FROM ACN 780224: THE ACFT HAD JUST COME OUT OF WEIGHING WHEN IT WAS RETURNED TO THE LINE.
