sharpie

Sharpie is a brand of permanent markers and related writing instruments produced by Newell Brands. The markers are known for quick-drying, durable ink that is designed to be water- and fade-resistant on a variety of surfaces.

The ink is typically alcohol-based and formulated for permanence. The product line includes fine point, ultra-fine point, chisel point, and broad point markers, as well as Sharpie Paint Markers and Fabric Markers. Sharpie markers are commonly used for labeling, drawing, and decorating on materials such as plastic, metal, glass, wood, ceramic, and textiles.

Sharpie was introduced in 1964 by the Sanford Ink Company and later became part of the portfolio of Newell Brands through corporate mergers and acquisitions. Over time, the brand expanded to encompass a wide range of marker types and colors, including specialty markers for outdoor use and education.

In practice, Sharpie markers are widely used in offices, schools, studios, crafts, and industrial settings. They typically produce permanent marks on most non-porous surfaces and many porous ones, though results can vary by material and marker type. Fabric markers may require heat setting to become durable on textiles, and certain surfaces may require surface preparation for best results.

Safety and handling notes indicate that Sharpie markers are marketed as non-toxic and often carry safety certifications such as ASTM D-4236. They should be used with adequate ventilation, kept out of reach of children when unsupervised, and not used on surfaces intended for food contact or ingestion.
