FAQ

Q. Is the cardboard rigid enough to prevent the mailer from bending during international transit? 

Yes. We use high-density virgin paperboard (300gsm-450gsm) that provides industrial-grade stiffness. These mailers are specifically designed to "Stay-Flat," protecting certificates, photos, and legal documents from creasing or folding under normal shipping conditions.

Q. What is the typical lead time for bulk wholesale orders with custom logos?

For standard wholesale orders, we ship within 7-10 days. For custom printed orders, the lead time is typically 15-20 days depending on the quantity and complexity of the design. We also offer expedited options for urgent requirements.
