This is the best label marker we've found. The Identi-Pen by Sakura. It has two tips, a fine fiber-tough point on one end, and an extra-fine plastic nib for details on the other. This pen will write on almost any dry surface, glossy plastic pot tags, glass, metal, CDs and fabric. It is permanent, waterproof, and most importantly, it resists fading from fluorescent lighting, sunlight and weather. We stock black only.
