Lean Labels are a great erasable label that can stick to any surface. This versatile system allows you to organize efficiently without the stress of a label machine. Simply pick which shape that will work best and use a Sharpie™ or water soluble pen to write directly on the smooth white PVC material. Need to fix or add something to it? No problem! Wipe it away with lacquer thinner (for Sharpie™) or water (for water soluble pen) and write away! Never been a better time to get organized!
