Review on 9-Inch URBNFit Pilates Ball For Yoga, Barre, Physical Therapy, Stretching & Core Fitness - Small Exercise Bender & Massager Ball With Workout Guide To Improve Posture And Relieve Back Pain. by Leonard Herrera

This unique inflatable exercise ball has flexible spikes throughout, Although these spikes may look a bit strange, these spikes are the very reason this is able to give a massage during an exercise. This ball is not a baby ball - It is a good 7-9 inches and very useful for roll backs or leg squeezes. Very easy to inflate and is stronger than any inflatable ball I own. No odor. Appears very well made.Btw, the packaging for this ball is AWESOME! Beyond AWESOME! And believe me, consumers care about quality, aesthetics and yes, packaging as well! Thank you, Urban Fit! I will be looking for all of your products.
