#10 Letter Size Mailing Envelopes for Business, 100Pcs Self Seal For Sale

What are the exact dimensions of these #10 envelopes in inches?

These are standard #10 business envelopes, measuring 4 1/8 inches by 9 1/2 inches (4.125" x 9.5"). This is the correct size for standard 8.5" x 11" letter-sized paper folded in thirds.

Is the self-seal adhesive strong enough for mailing without extra tape or wetting?

Yes, the self-seal closure features a secure, peel-and-press adhesive strip. It creates a strong, reliable seal immediately upon pressing, ensuring your contents stay secure during transit without needing moisture.

What is the paper weight (GSM or lbs) of the envelope material?

The envelopes are made from 24 lb bond paper (90 GSM). This is a professional standard weight that offers excellent opacity to protect the privacy of the enclosed documents and maintains a crisp, businesslike feel.

Are these envelopes suitable for use with a standard inkjet or laser printer for addresses?

Absolutely. These envelopes are printer-friendly and designed to feed smoothly through most laser and inkjet printers without jamming. They offer a smooth surface for clear, smudge-free printing of addresses or return information.

Is the paper opaque enough to hide contents when held up to the light?

Yes, we use a high-quality paper with good opacity (24 lb). When combined with the standard paper weight, the material ensures that sensitive information inside, like text or outlines of documents, is not easily visible through the envelope.
