These HiHats are in great condition. The edges and center holes are perfect. The serial # dates the matched pair to 2017 for both. The top hat weighs approximately 1016g and the bottom 1424g. The top hat "K" logo is slightly worn from cleaning. That is really the only issue with these hats. They sound great.
