Product Description – Mechanical Ring 3.0-ZERO Designed by ACEDC, the Mechanical Ring 3.0-ZERO is a sleek, minimalist fidget ring, measuring just 3.55mm thick and 8.9mm wide at the main body. Its faceted design provides a “zero-burden” wearing experience, offering a comfortable fit while delivering exceptional tactile feedback. The sensation of the spring beads as they move creates a surge of dopamine—once you start fidgeting, it’s hard to stop. Building on the success of its predecessors, the 3.0 model simplifies the design by replacing the Teflon bearing with POM buttons. The internal spring holes and grooves retain the original staggered configuration, allowing for easy adjustment between common and dense modes by simply repositioning the springs and beads.
