Brand new in the box - purchased direct from Herman Miller, where they had an MSRP of $179 plus taxes before selling out of their top of the line monitor arm. Fits up to 35" monitors. Fully brand desk products are sold exclusively by Herman Miller and Design Within Reach only, which attests to their quality and durability. The Jax Single Monitor Arm by Fully in Black is sleek, stylish and highly functional. We do not have any double monitor arms, but two singles would offer more versatility and placement. Great reviews where these were sold on Amazon before the brand Fully signed to only exclusively sell through Herman Miller and Design Within Reach. See link below.
