Open Side Booklet Envelopes for High-Volume Mailing

Quality Park 37613 envelopes are white business envelopes sized 13 by 10 inches and sold in a 100-count box. The open-side design on the long edge allows quick insertion of booklets, catalogues or multi-page documents. A 28 lb stock weight provides a professional feel for everyday office correspondence.

Check Document Dimensions and Printer Compatibility

Verify that your materials fit within the 13 by 10 inch envelope format before ordering. Confirm that your printer or copier feeds this paper size without jams, as larger envelopes can misfeed on some desktop machines. Ensure the gummed flap sealing method suits your workflow compared to self-seal or clasp alternatives.

Upgrade from Standard Letter Envelopes for Bulk

These replace standard letter-size envelopes when mailing thicker booklets or unfolded sheets that exceed letter dimensions. The deep flaps and wide gumming create a more secure seal for heavy contents during transit. The jump is worthwhile for offices that regularly send catalogues, proposals or reports requiring a flat, professional presentation.
