Set Collaboration Free. The Post-it Super Sticky Dry Erase Surface is designed to stick to a variety of painted drywall and steel surfaces, glass, finished wood, and existing whiteboards or chalkboards. The Post-it Super Sticky 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 Super Sticky 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 Super Sticky 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.
