When unique orders come through, be prepared with Quality Park Jumbo Catalog Envelopes. They’re oversized to accommodate tall contents, whether that be banners, contracts or diagrams. While paper can always be folded to fit inside an average envelope, it’s best to maintain that crisp, crease-free look. So use the open-end slot to insert files, seal it off by moistening the split gum adhesive and send it on its way.
