Professional-grade ID labels feature extra-strong adhesive that is ultra-permanent and sticks to almost anything, including wood, metal, glass, rough plastic and cement. Durable material can withstand moisture, scuffs, tearing and moderate cleaners; such as ammonia, hand sanitizer, bleach and soap. Water-resistant, tear-resistant labels are great for quick labeling of tools, equipment, bins and various objects around the warehouse. Handwrite on the 4" x 6" sheets using a permanent marker for long-lasting identification (standard ink will wash off). Each sheet includes 12 labels (3/4" x 1-3/4").
