Due to the high coating on your Toní products, you can easily remove scratches yourself. Use a scouring pad with soap and water or all-purpose cleaner and rub over the scratch. The scratch will disappear.
You can use this on these kind of scratches where you don't see the black metal.
Do you have a deep scratch on your Toní? Then you can restore it with the Retouch pen. This contains 12 ml of lacquer that you apply to the scratch.
