Rollga Hand and Foot Ultra-Soft Therapy Massage Ball and Stress Ball Kit

Those balls is very small.I return back

(Take it for granted--I know this isn't the prettiest picture you've ever seen.)The gray ball is about the size of a tennis or racquetball, the orange about the size of a ping pong ball. They are made of a very soft material, kind of like a gardener's kneeling mat, maybe softer, a bit denser. Surface has a slight texture which gives the balls a little grip for your skin so they don't go shooting across the room as you use them. They become slightly misshapen under pressure, but return to shape afterward.These are great for tender feet, but also great for any feet. They allow you to roll and squish your foot down onto them so you can get relief without excessive pain. They conform to the shape of your foot like no other product I've found.I'm so happy with these I've ordered a second set--I know I'll use them.

Very good quality . Perfect for use on the airplane . Durable as well .

these really open up my hands and loosen them nicely
