Can 4OVER4 ship my printed materials in a USPS flat rate envelope instead of a box?

4OVER4 ships printed materials like business cards in small corrugated boxes rather than USPS flat rate envelopes, and it comes down to protecting your order.

• Corrugated boxes shield cards and cut stock from bending, crushing, and moisture in transit.
• Flat rate envelopes are handled more roughly and offer little protection, so damage risk is higher.
• 4OVER4 cannot control how USPS processes envelopes, so a box is the safer default for every job.
• Boxed packaging keeps corners crisp and finishes intact, which matters most on premium stocks and coatings.
