What we like best about these tapes is that you can mark the matte blade surface with a pencil, allowing you to use the blade like a story stick for direct reference. The case also has a scratch pad for measurements or simple diagrams. You can erase pencil marks on both the tape and the pad just by rubbing them with your thumb. There's even a built-in sharpener for standard pencils. Rubberized for grip and impact resistance, the case has a lever-action clip that hooks easily onto your belt. Two tape styles are available, with color-coded cases for quick identification.
