Used, but virtually new.
 
The Encore NZ3B Nancy Zeltsman "Medium Hard" mallets are the most versatile mallets in the line. They sound excellent in all registers, particularly the middle of the instrument (from about C3 to C6). 

The oval-shape of the mallet head is horizontal rather than vertical. Everything about the construction of these mallets-from the cores, to the latex, to the type of yarn-is aimed at helping you to produce a fundamental-rich tone.
