This 17" device is designed to not only be able to scratch that menacing itch but allow you to be able to use wet wipes and alcohol swabs in a safe non-irritating way to keep your arm or leg clean and comfortable. The handle can be used if youre in need of a deep/ firm scratch. Use the other end for a slightly more gentle touch. In addition, the smaller end allows for insertion/ attachment of an alcohol swab to keep any sores disinfected or a simple wet wipe to cleanse and remove smell and dead skin allowing for an itch free/ clean cast wearing experience.
