Abstract
Examples of a print particle transfer device are described herein. Some examples of the print particle transfer device include a print particle vessel to contain print particles. In some examples, the print particle transfer device also includes a plunger with a fibrous seal element to engage an inside surface of the print particle vessel. The fibrous seal element seals an interface between the plunger and the inside surface of the print particle vessel to prevent escape of the print particles at the interface during movement of the plunger within the print particle vessel.
