We purchased all of the sheet music from a local store that closed their doors. If the sheet music is listed in "like new" condition it is unsold sheet music with a very minor condition from sitting on store shelves over the years.
If it is listed in "very good" condition it is most likely used sheet music (typically has minor edge wear, dog ear corner, or very tiny split in the seam) I list the specific issue (if any) in the seller notes above. I should also say I will not sell sheet music that is brittle or has writing or torn pages.
Check my seller feedback of 100% positive for over 5000 listings. I stand behind every item I sell...... thx
