The combination of the BLACKROLL® BLOCK, MINI, and BALL 08 is rightly known as the "Swiss army knife" of fascia tools. The targeted massage of individual muscles and parts of the body, such as the chest, hand, foot, arm, or calf, is made many times more effective. The BLACKROLL® BLOCK complements and extends the application possibilities of BLACKROLL® products. You can combine the smaller BLACKROLL® products with the BLACKROLL® BLOCK as needed to exert higher pressure or reach certain parts of the body more easily. The BLACKROLL® BLOCK set complements and extends the application possibilities of BLACKROLL® products. The BLACKROLL® BLOCK is a multipurpose tool with an open bottom, perfect for stowing a BLACKROLL® MINI or a BLACKROLL® DUOBALL 08 and a BLACKROLL® BALL 08.
