The soft-touch area of the guitar hanger is made from a premium grade of pure silicone with no additives. It is safe to use with common, properly cared for guitar finishes. We take the responsibility of protecting and showcasing your guitar seriously. Since there are some factors outside of our control like the age of your instrument, previous cleaning routines, and environmental conditions, we recommend you periodically inspect your guitar's finish after use to make sure it still looks great. If you ever notice any changes in your finish, please discontinue use immediately and please let us know. For long term storage or extended periods of unuse, we recommend that you keep your instrument in its original case in a safe environment. Strumland assumes no responsibility for the use of our products beyond the product's specific intended design or when improperly installed. We are always testing and appreciate hearing customer feedback. Please contact us if you have any questions or would like to share your experience with us.
