Three-ring poly envelopes solve the dilemma of how to put important documents and keepsakes, such as deeds, abstracts, contracts, photos and brochures into a standard three-ring binder. Each clear poly envelope features a three-hole punched flap and fits into a standard binder. Flap has a hook-and-loop closure. Envelope expands to hold up to 1-1/4″ , allowing easy viewing and protection. Poly material is water-resistant, tear-resistant and is easy to clean.
