ENVELOPE WHITE C4 SELFSEAL(ENVWHI09)

The C4 White Self-Seal Envelope (ENVWHI09) is a premium mailing solution designed for professionals who want to make a clean and polished first impression. Made from high-quality, bright white paper with a smooth finish, these envelopes are perfect for high-profile business correspondence, portfolios, and official certificates. Sized at $229\text{mm} \times 324\text{mm}$, they are specifically designed to fit full A4-sized documents without the need for folding, keeping your reports and contracts flat and pristine during transit.

This envelope features a modern self-seal adhesive strip, which provides a fast, hygienic, and incredibly secure closure. The “peel-and-seal” mechanism ensures a permanent bond that protects the contents from slipping out or being tampered with. The high opacity of the white paper ensures that your documents remain confidential and are not visible through the envelope. Whether you are sending a job application, a luxury brochure, or a legal agreement, the ENVWHI09 combines a professional aesthetic with the practical durability needed for the modern postal system.
