Thank you very much for viewing. This item is "Pearl Drum Heads, 4 Black Beat (16", 14", 13", 10") - not sold separately." These were removed from a drum set I'm currently using as a sub. I replaced them with new heads, so I no longer need them. I'd like to pass them on to someone who can use them. The 10-inch and 13-inch heads have gold hoops, while the 14-inch and 16-inch heads have silver hoops. They may be from different manufacturing periods. I think I've used them for nearly 10 years, but since they are the bottom heads and not the batter heads, they haven't worn down much and I think they can still be used. However, since they are old used items, I strictly refuse purchases from those who are concerned about minor scratches, those who are nervous, those who seek the same quality as new products, and those who reflect their impressions of the product in their evaluation. I will wrap them in bubble wrap and ship them in a recycled cardboard box. Thank you for your consideration. ※ I am also listing many other drum-related items. I would be grateful if you would take a look.
