I enjoy using these rollers whenever I notice the bags under my eyes are too puffy, or whenever I feel a tension/tmj headache start to surface. This helps to gently massage my temples without further aggravating the issue, keeping it at bay until I’m able to deal with it better. I would have loved to have helpful instructions or a tutorial video on how to best use these for the various benefits, but I’m glad I have them at the ready when I do need them at home, and can take them with me to work if I need to.
