The small size wooden roller - middle to upper back.
It's easy to massage or crack your back using my wooden "foam" rollers. A wood roller is so much better than a foam roller! Wooden rollers are totally natural, adjustable and don't out-gass chemicals! Also, wooden "foam" rollers will last for many years!
*** (Remember, if you are injured please see a doctor, massage therapist or chiropractor. Please also be careful when starting out with foam or wooden rollers. Start out easy and increase pressure as you get stronger and more pliable.) ***
These massage tools can do wonders for tight backs, legs and buttocks and really help you to heal and feel better fast! I use my wooden rollers every day and love them so much!
