The Nuphy Twotone wrist rest is constructed of a precision-machined acrylic module and an aluminum module joined together, the wrist rest is as great a Halolight companion as your wrists. The acrylic top diffuses the RGB lights emitted from the LED ring, completing the amazing Halo effect, while the solid aluminum base provides support and strengthens the structure.
