In our law and real estate office, we handle hundreds of leases of various properties ranging from residential to commercial. The Tuff File expansion pockets paired with Smead's classification folder with dividers (item #19075), allow us to manage four to six properties' leases, insurance, correspondence and other details in one file cabinet stop. We organize the information efficiently, neatly, and well-organized in order to have the least amount of stress when reaching for them. We label the tabs by business entity and the classification folders by property name/address. They are "virtually indestructible"!!! Thank you SMEAD for your high quality products at a valuable price! Your products have lasted us many years, and we will always be loyal to you!
