About this item

• ✮Perfect Design For Comprehensive Massage✮- 5" in length and 2.5"in diameter, weight in 12oz. This split peanut-shaped massage ball is a perfect design to get to those hard to reach stabilizing muscles that surround your spine and vertebrae without applying pressure on them as you lay on it.
• ✮Durable Material✮- The massage ball is made of 100% natural rubber, which is firmer than tennis ball, but not like the hard plastic balls with knobs and they hurt. It is durable for long-lasting use. 4 colors have the same density for choice.
