At least one is missing.
Bryan Milner sent the package from Cedar Park, Texas on November 10.
"There are legal documents," Milner told Eyewitness News. "There's a five figure check as well. This was all settlement money from a lawsuit."
According to the tracking information, the documents still have not been delivered as of December 6.

"It's very, very time consuming," said Milner. "It's taken me away from my work."
We spoke with Milner via Skype from his home, where he works for attorneys handling documents. Even after multiple conversations with someone in customer complaints, he says nobody has found what he sent.
"I'll never use them again," he said.
He's not the first to complain about this facility. A year ago, we reported about more than 1,000 complaints we received about slow delivery and lost packages. At the time the postal service told us it was upgrading equipment and adding as many as 750 employees to better serve customers.
On Tuesday, they sent us a statement which read, in part, "The Postal Service is continuously striving to improve service to our customers. At the North Houston Processing & Distribution Center, we have taken a number of proactive steps to ensure the most efficient and timely handling of mail. "
Milner isn't happy.
"I should have used UPS," he said. "I should have used FedEx."
However, both UPS and FedEx have merchant options called SurePost and SmartPost in which they handle the shipping and the postal service handles delivery. If you want to opt out and only use private carrier, UPS told Eyewitness News to set an automatic upgrade option for a small fee on its UPS My Choice website.
FedEx says shipping is a transaction between merchant and customer and they don't control the shipping option.
