Onyx - SAF3612BL Onyx Mesh Marker Organizer with Basket is a magnetic whiteboard accessory that allows easy storage of dry-erase markers and erasers. It includes four stand-up marker holders that fit most standard whiteboard dry-erase markers, making it easy to grab a marker when needed and helping to ensure markers are stored upside down so that they last longer. The magnetic back allows use on whiteboards or any other magnetic surface, and features Rare Earth Magnets that are strong enough to work on Magnetic Glass Marker Boards as well as standard magnetic whiteboards. Caddy also includes a basket that can hold erasers, markers or other supplies for easy access. This organizer also offers the option of mounting to a wall with use of steel plate (included). Sturdy steel wire mesh construction of this caddy has a black powder-coat finish for scratch-resistance and chip-resistance. Rolled edges are smooth to the touch and give a polished appearance.
