They all arrived in identical packaging.

The five apparent pipe bombs sent to former President Barack Obama, Hillary Clinton, CNN’s New York City headquarters and others were each placed in a nondescript manila envelope lined with bubble wrap, the FBI said Wednesday.

The mailers all bore six American-flag “Forever” stamps and computer-printed address labels.

“All packages had a return address of ‘DEBBIE WASSERMAN SHULTZ’ [sic] in Florida,” the FBI said in a statement

The envelope sent to former CIA Director John Brennan at CNN offices in Manhattan also had his name misspelled, as was Rep. Debbie Wasserman Schultz’s home state, according to photos released by CNN.

That envelope didn’t bear a postmark, and law-enforcement sources told CNN it was delivered by a courier.

Photos of the device show a cylindrical object, about six inches long, wrapped in black electrical tape and with wires emerging from either end.

The wires — one red and one black — lead to a digital clock or timer taped to the middle of the tube.

A senior law-enforcement official told The New York Times that it resembled the others, saying, “Same package. Same device.”

The FBI described the devices as “potentially destructive,” and law-enforcement sources told The Post that the first one discovered — in a mailbox outside the Katonah home of billionaire George Soros Monday — had black powder on it.

But a source briefed on that device and the one sent to CNN told The Post on Wednesday that they couldn’t actually have blown up because neither was equipped with a blasting cap or other means of detonating explosive material.

“There was nothing to ignite it,” the source said. “There was nothing there.”

The source also said an envelope of unidentified powder contained in the CNN package was too small to create a radiological or biological “dirty bomb.”

The fact that none of the bombs blew up suggests they were built by an amateur, former FBI Agent Steve Gomez told ABC News.

The NYPD used its rarely seen Total Containment Vessel to move the CNN device from the network’s bureau at the Time Warner Center in Columbus Circle to the Rodman’s Neck police facility in The Bronx.

Members of the department’s elite Bomb Squad carefully loaded the device into the back of the TCV, placing it onto a suspended net inside the chamber designed to minimize jostling, police sources said.

The TCV, which is mounted on the back of a NYPD Emergency Service Unit truck, is engineered to withstand a blast from within should the device trigger during the trip, minimizing damage to those outside.

In the early afternoon, police blocked off a route to Rodman’s Neck, providing the TCV with quick access to the facility with minimal risk to motorists.

Escorted by a convoy of emergency vehicles, the TCV wound its way to the remote firing range and training facility.

Now, technicians from both the NYPD and FBI are figuring out how to safely transport the device to federal labs for further examination, NYPD Deputy Commissioner of Intelligence and Counterterrorism John Miller said in a press briefing.

The process is being hampered by the envelope of powder included in the package with the bomb, Miller said.

Ideally, investigators would like to disarm the bomb without detonating it, allowing them to comb over it for any clues to the maker’s identity, including fingerprints and DNA, sources said.

A TCV was also used to transport one of Chelsea bomber Ahmad Khan Rahimi’s undetonated pressure-cooker explosives to the facility in 2016.
