This is an innovative product that turns any flat surface into a guitar rest. It's easy to use: simply place the PW-GR-01 on the edge of a flat surface and lean your guitar against it in the neck pocket area. The surface friction prevents the guitar from moving. It's a very convenient item when you need to temporarily rest your instrument without a guitar stand. *This product has been thoroughly inspected and designed to safely support guitars with all finishes. However, we do not guarantee against damage to the instrument caused by tipping or finish melting.*
