It’s about time someone killed off the dry-erase board—the heavy, smudge-filled fixture of offices everywhere. The Post-it Flex Write Surface is just the dry-erase slayer we’ve been waiting for. Available in 3- to 50-ft. rolls, the Flex Write is effectively a whiteboard sticker that you can unroll, unpeel and slap wherever. “My son’s calculus class got some and covered a whole wall,” says Amy Hester, a 3M product developer. Thanks to some next-level office-supply science, the Flex Write Surface ($36 for 3 by 2 ft.) works with either dry-erase or permanent marker. “When you spray water on the permanent ink, you can actually see it lift and wash away,” adds Hester. —J.R.
