Description
From the sellerThe Onesti Key Balance Hole Repair System is a professional tool kit and methodology created by Registered Piano Technician (RPT) Ralph Onesti. It is designed to quickly, accurately, and permanently repair worn, oblong, or damaged balance rail holes in piano keys. Set includes tools and wooden plugs. As far as I know, this kit is not available anymore, so it can be hard to find.
