## Long description

The NC Koperty B4 brown gusset envelope is a professional-grade mailing solution designed to provide secure transport for bulky documents, catalogs, and thick files. These envelopes are constructed from durable brown paper, offering a reliable barrier against external elements during transit.

When it may not be suitable
This envelope is not intended for shipping fragile or liquid items that require rigid protection or moisture-proof packaging. It is also not suitable for extremely heavy objects that exceed the structural capacity of standard paper mailing supplies.
Key specifications

Material: Durable brown paper
Closure type: Self-adhesive strip

How to use
To use the envelope, insert your documents or items into the main compartment, ensuring the gusset is fully expanded to accommodate the thickness of the contents. Peel off the protective strip from the adhesive flap, fold the flap down firmly, and press it against the body of the envelope to create a secure, permanent seal. Ensure the surface is clean and dry before sealing to maintain the integrity of the adhesive.
What to consider before purchase
Verify that the B4 size is appropriate for your specific document dimensions
Ensure the thickness of your items does not exceed the capacity of the gusset
Check if the weight of your contents is suitable for paper-based mailing
Usage recommendations
For optimal security during transit, ensure that the adhesive strip is pressed firmly across the entire width of the flap. If mailing sensitive documents, consider adding additional reinforcement or using a tracking service for important shipments.
