This peanut roller is built for users who find softer tools ineffective. The dual-ball design follows the natural channels along the spine and other narrow areas, applying focused pressure where single balls shift and foam rollers lose precision. The raised surface texture increases grip and contact, helping the roller stay stable under body weight while allowing controlled movement on the floor or against a wall. Made from high-density EVA foam similar to firm foam rollers, it delivers minimal compression and consistent resistance with repeated use. Its compact, one-piece construction fits easily in a gym bag or carry-on and holds its shape over time. Designed for control, pressure, and durability, it’s a straightforward tool for targeted self-massage without bulk or moving parts. Specifications: Material: High-density EVA foam Dimensions: 5.1" L x 2.5" W Firmness: Firm, low compression Use surfaces: Floor, wall, mat
