Expanding wallet with built-in, integrated tab is made with special water-resistant redrope material to protect your files. The material also resists spills, dirt and finger oils. Tear-resistant gusset is made of fully lined Tyvek and features rollover reinforcement at the top. The gusset extends 7/8" into the front and back panels twice as far as standard expanding wallets for super Tuff bonding strength. Protective flap is Tyvek-reinforced and has an elastic closure. Built-in tab makes it easy to label. Extra-wide wallet also allows top-tab file folders to fit neatly inside without bulging out the sides. Wallet expands 5-1/4".
