With key. With strap. This 511 was used as the main recorder, more so than the 311 I also had, so it has some dirt. When using the strap, I attached a finger rest with glue, so glue residue remains on the side of the recorder and inside the finger rest. Please check the photos before purchasing. The sound comes out properly. - Brand: AULOS - Model: TENOR 511E Thank you for looking.
