A hollow-core EVA roller made with a moulded surface, so the outer layer can carry wave, grid, groove, raised-point or hybrid patterns. The raised geometry concentrates pressure for targeted muscle release, while the hollow PVC or ABS core keeps the roller light and gives the tool its stiffness. It is intended for recovery, mobility, warm-up and massage work, and the depth and spacing of the pattern change how intense the roller feels in use. Surface pattern, texture depth, diameter, length, EVA density and colour are all specified per order, so confirm the geometry before production.Key details:Materials: EVA outer layer with a hollow PVC or ABS core
