[Size *Please consider these as approximate sizes] Thickness = Approximately 10.08mm Width = Approximately 39.23mm Length = Approximately 74.12mm Hand-carved from a Hinoki (Japanese cypress) square timber. This is a wooden piece to be inserted between the inertia block of a Stratocaster to secure the bridge. Sanded to a high grit, it has a very silky feel despite being unpainted. All corners are rounded, so it won't scratch your guitar. Since the gap size varies for each guitar, please adjust the thickness by sanding or using tape, etc., to set it. Returns due to size differences are not accepted. Because it is all handmade, it has a strong handmade feel. Please refrain from purchasing if you are looking for precision.
