This modular system has three different ways to be built to help you fit it into your space, and it\'s perfect for accomodating most pens! Ever since we first launched the Spectrum Noir pens, we’ve been working on ways to best store them. Due to the nature of alcohol pens, they need to be stored horizontally to ensure even ink flow to both ends. With this in mind, we\'ve developed a versatile storage solution that fits not only Spectrum Noir pens, but also all pens up to 17mm (5/8”) in diameter, including specialised colouring systems. Each unit will hold 12 pens - the perfect size to hold two fulls pack of colour-themed Spectrum Noir pens - and they can be stacked as high or as wide as you require.
