Splendoress #10 Self-Seal Envelopes, 500 White Windowless Security Envelopes

Splendoress #10 self-seal business envelopes are made for mailing correspondence, with a 24 lb rating and a 100% tinted security interior.

• 500 envelopes per box — keeps a bulk supply together for regular mailing.
• #10 size, 4-1/8 x 9-1/2 inches (10.5 x 24.1 cm) — gives you the stated dimensions for choosing an envelope.
• Peel-and-seal flap — close each envelope without licking it.
• 100% tinted interior security pattern — helps prevent the contents from being seen through the envelope.
• NDAA Section 889 compliance certification — provides a stated compliance credential for the product.

For offices and other routine mailing needs, these envelopes combine a plain, windowless exterior with a closure that does not require moisture. The interior security pattern is designed to obscure what is inside, while the bulk count suits ongoing correspondence rather than a one-off mailing. Their white finish keeps the outside simple for regular business use.

How do the Splendoress #10 envelopes seal?

Each envelope has a peel-and-seal flap: remove the peel-off strip, then press the flap closed. This lets you seal correspondence without licking the adhesive. The closure is built into the envelope, so there is no separate sealing step that requires moisture.

• Peel-and-stick closure is part of the envelope.
• Designed for convenient, routine mailing.

What size are these Splendoress envelopes?

They measure 4-1/8 x 9-1/2 inches (10.5 x 24.1 cm) and are identified as #10, letter-size envelopes. Compare these dimensions with your mailing needs when selecting a size. The plain white design has no viewing window, so the envelope exterior does not expose an address through a window.

• Regular, plain envelope style.
• Windowless construction.

How many envelopes are included, and what protects the contents?

One box contains 500 white envelopes, each with a 24 lb rating. A security printing pattern on the inside is intended to keep the contents from being seen through the paper. The 100% tinted interior gives this windowless mailing format an added privacy feature for correspondence.

• 500-count box for a longer-lasting mailing supply.
• NDAA Section 889 compliance certification.

Splendoress #10 envelopes suit businesses and individuals who regularly send correspondence and want a no-lick closure with a tinted security interior. Their stated size, plain windowless format, peel-and-seal flap, and 500-count box make them a practical fit for routine mailing needs.
