This is a standard modern corded handset used on 500/2500 series phones from the mid 50s through the present.  It is suitable for use with cup hooks or space savers in locations where there isn't too much noise.  For noisy locations, we recommend the G5 push-to-talk handset.  We offer this part new in black and used in various colors as we have stock.  Used equipment is offered in "Gently Used" condition (complete handset cords in good shape and only minor cosmetic damage) and "As is" which is functional but has been "Rode hard and laid up wet" including minor repairs.
