Industry Marks are reusable camera, actor and dolly mark. They are come in 13 different colors including Glow-in-the-Dark and closely match the paper tape used for marks. A soft but very durable clear plastic coating protects delicate floors from being damaged. Number the marks using a ballpoint pen. The ink will come off by either wiping off the ink with your finger or they can be cleaned with regular soap and water. Industry Marks were created for AC's who are tired of lugging around large heavy sandbag marks. The L and T marks weigh less than 4oz and the I marks weigh 5oz or less. These next generation marks are more durable, lighter, cheaper, and overall a more practical solution to reusable marks.
