Quality Park Filing Envelopes - File - 11 3/4" Width x 9 1/2" Length - 7 lb - 100 / Box - Travelling with prints, proofs and drawings is easy thanks to Quality Park Flat Index Files with Flap. Through the side opening is a spacious interior ideal for preserving precious cargo, such as significant group or personal projects. The flap encloses the contents, but because it lacks adhesive, it can be opened and closed as often as necessary. Not only that, but the smooth finish and supportive construction exude professionalism.
