Set collaboration free. The Post-it dry erase surface allows you to easily transform painted drywall, glass, painted steel, finished wood or even old whiteboards and chalkboards into a pristine, dry erase board. The Post-it dry erase surface is easy to install and requires no tools - just unroll, peel and stick. Utilizing a proprietary dry erase coating, the Post-it dry erase surface is stain-proof, erases cleanly every time and writes smoothly. From horizontal applications on desks or tables to vertical applications on surfaces where traditional whiteboards cannot be installed, such as windows, the Post-it dry erase surface can be cut-to-fit and provides endless possibilities for dry erase solutions in new places. It's even great for replacing old dry erase surfaces that may be ghosted-simply apply over the existing board and it looks new again.
