A hollow-core foam roller whose EVA outer layer is produced in mixed or dual colours, so the surface shows a blended or gradient effect rather than one flat shade. Like other hollow rollers it is lighter than a solid version, and the firm outer skin allows controlled pressure for mobility work, warm-ups and post-workout release across the legs, back and shoulders. Colour combination, core colour, diameter, length and EVA density are produced to order. Confirm the exact colour pairing and finished dimensions before buying, particularly if the roller needs to match an existing range.Key details:Materials: EVA outer layer with a hollow PVC or ABS core
