Onyx Mesh Marker Organizer with Basket is a magnetic whiteboard accessory that allows easy storage of dry-erase markers & 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 & 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, & 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 & chip-resistance. Rolled edges are smooth to the touch & give a polished appearance.
