It can be hard to apply lotion and soap to certain parts of the body, like the back. If you don't have someone to do it for you, a tool like this is a necessity. Simply fill with a favorite lotion and use it to apply lotion to the back or other hard-to-reach areas. Can be used all over the body; ideal for the lotion user who doesn't want lotion all over his or her hands. Measures nearly 18" long.
