The BIC Intensity Permanent Marker 40-count set delivers bold, long-lasting color for home, school, office, and creative projects. This Costco-exclusive set (model GPMX40CT) includes a mix of ultra fine and fine tip markers in a wide range of assorted colors, giving you versatility for both detailed line work and broader coverage.

BIC Intensity markers feature low-odor, acid-free ink (no added acid, no measurable pH) that creates vibrant, fade-resistant marks on virtually any surface — including glass, metal, photos, foils, coated paper, plastic, and even oily or damp surfaces. Each marker is equipped with a unique snap cap featuring a vapor seal locking mechanism that prevents dry-out and extends marker life. The smooth plastic barrel includes a soft, non-slip grip for comfortable, controlled use during extended coloring or writing sessions.

These markers are ACMI-approved and non-toxic, making them suitable for adult coloring pages, doodles, art projects, labeling, and general use. The durable tips resist wear-down to maintain consistent line quality throughout the life of the marker.
