Durable fine point tip writes on cold, wet surfaces as easily as it writes on dry ones. Quick-drying, alcohol resistant ink provides permanent markings on plastic disposable ware. On glass, metal or porcelain surfaces, ink will not bleed when subjected to water or alcohol during normal use. The xylene-based ink can, however, be washed off these surfaces, allowing them to be relabeled. Fine tip has a line width of 1mm. Available in four colors.
