4 balls of different colors packed in a nice color box, available in 2 sizes targeting different areas of the body.
4 Balls: 2x7.5cm (yellow, red), 2x9cm (green, blue)
The Spiky Massage Ball is also called Porcupine Ball. It has a lot of sensory nodules that act as mini acupressure points when rolled along the body. These nodules can penetrate down to the muscle layers helping increase blood circulation, reduce stress, and comfort the underlying tissues. Ideal for self-massage or with assistance to treat back pain, ease tension, stimulate the nerves and energize the whole body.
This pack includes 4 balls in 2 sizes, providing different levels of stimulation, and targeting different areas of the body according to users' preference. Color box packaging and ideal as a gift too.
The color box says 'Hard & Soft ball Combo'. Please disregard this message. Reasons: the density of soft balls is just little less than hard ones in order to stay functional, thus users may not feel difference.
Meet or exceed consumer product safety requirements of EU EN71, US CPSIA & ASTM F963 Standard. Safe to use.
