Half your lesson dies on a single-sided board. You're mid-diagram and there's no room for the notes that go with it. Quartet Flex fixes that. One face plain for sketches and flowcharts, the other lined for structured notes or student work. PET construction takes a beating and keeps writing clean between uses. Thirty boards in the pack means you're not raiding the supply closet every Tuesday. Grab a pack and stop losing the second half of your lesson
