Abstract
A print material refill container includes a housing and a chamber, within the housing, to contain a print material. The print material refill container includes a physical indicator subject to modification based on an engagement of the physical indicator with an engagement member of a printing device when the print material refill container engages the printing device to deliver the print material to a reservoir of the printing device. The physical indicator indicates an unused condition of the print material refill container when the physical indicator has a first state prior to the modification, and the physical indicator indicates a used condition of the print material refill container when the physical indicator has a second state subsequent to the modification.
