The Blackroll Balls with 8 cm and 12 cm in diameter are ideal for targeted self-massages on different areas on your body. The two sizes perfectly complement each other in their respective uses: depending on the effect you want to achieve, you can use the 8 cm ball for a highly directed massage that zeros in on specific tight spots and the 12 cm ball for a massage that covers a larger area with less pressure.
