What type of product is sold by the characters on the TV show "The Office"?

The characters on The Office sell paper products through the fictional Dunder Mifflin Paper Company. The American series centers on employees at Dunder Mifflin’s Scranton, Pennsylvania, branch, where sales staff serve business customers.

Dunder Mifflin is primarily portrayed as a regional paper supplier rather than a paper manufacturer. Salespeople such as Michael Scott, Jim Halpert, Dwight Schrute, and Stanley Hudson compete for office accounts, negotiate prices, and try to retain clients in a changing business environment.

The show also mentions related office and janitorial supplies, especially after the company expands its offerings and is acquired by Sabre. Still, paper is the defining product and the central running joke: the employees work in a paper company, yet spend much of their time dealing with relationships, rivalries, and office chaos rather than selling.

The company is fictional, but Dunder Mifflin merchandise and branded products were later sold in the real world.
