You've tried the 'premium' pens from the big box store and they dry out by Thursday. The Zento line is different. Ultra liquid ink that flows smooth and stays flowing, in a box of twelve assorted colours. Whether you're colour-coding a Gantt chart, marking up a site plan, or just need a pen that doesn't ghost on page three, this is the one that keeps up. Twelve pens, one box, no more rummaging for a working one
