Thanks to the proven three-dimensional GRID surface technology and the new hand-rolling system, fascia tissue can now be comfortably treated while sitting. The specially designed handles, AcuGRIP, also serve as a massage tool. The rounded, flat ends and the protrusions on the handle allow for targeted and precise trigger point treatment. Furthermore, the GRID STK can be used on body areas that cannot be reached with a traditional foam roller, such as the neck muscles. The GRID STK can be used preventively, for recovery, and to enhance performance at home, in the office, and while traveling. Its water-resistant surface makes it easy to clean. Based on the idea of mimicking finger structures during massage, the GRID STK features different surface textures. It consists of a softer outer roller that is interspersed with a grid of indentations at varying distances. This revolutionary design, with its various massage zones, allows for different treatment intensities depending on the body region. 3D surface texture, ideal fascia care through innovative GRID surface technology. AcuGRIP, specially designed handles ensure more targeted treatment application. Comfortable use, treatment is now also possible while sitting. Water-resistant, the surface is water-resistant and thus optimal for cleaning.
