A worker at the Gillette plant in South Boston and two accomplices have pleaded guilty to federal charges that they stole shaving cartridges hot off the assembly line to sell on eBay, the US Attorney's office in Boston reports.

The World Shaving Headquarters worker, Joseph Evangelista, 63, of Lowell, pleaded guilty to one count of causing the interstate transportation of stolen property. His two accomplices, Robert A. Liberatore, 52, of Wakefield, and Mark S. Girardin, 44, of Randolph, each pleaded guilty to two counts of filing false tax returns.

According to the feds, in 2011, Evangelista handed over hundreds of Mach3 and Fusion ProGlide blades to Liberatore and Girardin, who would then package them for shipping in an apartment on Cambridge Street in Cambridge that they rented for that purpose. The sold a total of $209,000 worth of blades between February and August of that year, according to court documents.

Liberatore and Girardin also sold non-Gillette products online - but declared none of their sales on their federal taxes.

The three are scheduled for sentencing on Nov. 6.
