With this in mind, Spectrum Noir developed a versatile storage solution that fits not only Spectrum Noir markers, but also all pens up to 17mm (5/8”) in diameter, including specialized coloring systems. This fabulous modular system can be built up in three ways, great for fittings lots of different workspaces. Stack them vertically, horizontally, or angled – the interlocking design makes it so easy to put together and enables you to add to your collection. Stack them as high or as wide as you desire. Each tray holds twelve Spectrum Noir markers, and with six trays in this set you will be able to store 72 pens in total. It’s not just colorists that will love this versatile storage system – if you’re a jewelry maker with lots of long, narrow tubes of delicate seed beads then this is a great way to organize them all so that you can see at a glance all the different colors and styles.
