The Q-Connect Gusset Envelope (KF3528) is designed for professionals and office administrators who need to mail bulky documents like catalogues, reports, and brochures safely. With a 25mm expanding gusset and high-quality 120gsm manilla paper, it offers reliable protection for thicker items, though its rigid construction may not be suitable for small, standard-sized letters that require a lightweight, flat profile.

While you can, they are oversized and designed for bulky items; standard envelopes are more cost-effective for thin, single-sheet letters.
No, these envelopes feature a self-adhesive peel-and-seal strip, so no moisture is required.
These envelopes are made from durable 120gsm manilla paper.
The manilla paper used is a standard wood-pulp product; please check your local recycling guidelines for paper disposal.
Each pack contains 100 individual envelopes.
The expanding gusset measures exactly 25mm.
Ensure the surface of the paper is free from dust and debris, and press firmly across the entire flap for 5 seconds.
Ensure the contents are stacked evenly; if the stack is thicker than 25mm, do not overstuff as it may compromise the seams.
To ensure the best results, place your documents neatly into the envelope, ensuring the edges are not caught on the gusset folds. Peel the adhesive protective strip away firmly and press the flap down evenly across the entire width of the seal to ensure a complete, air-tight closure. Store these envelopes in a cool, dry place; excessive humidity can cause the adhesive on the peel-and-seal strip to lose its tackiness or cause the manilla paper to soften.
