Aimoh #10 Single-Window Mailing Envelopes Letter Size 500-Count — Self-Seal, Security Tint

Aimoh #10 Single Window Mailing Envelopes are letter-size, self-sealing security envelopes sold in a 500-count pack, designed to protect contents while speeding up bulk mailing.

These Aimoh #10 envelopes combine a large, easy-to-read poly window with a security tint interior and a rapid peel-and-seal adhesive strip, making them a practical choice for offices that send invoices, statements, or other mailings regularly. Each envelope measures 4-1/8 x 9-1/2 inches and includes a 4-1/2 x 1-1/8 window positioned for standard printing and addressing. The reinforced adhesive creates a strong closure that resists tearing, and the inside wave pattern obscures text and numbers for added privacy.

How do these envelopes make bulk mailing faster?

Aimoh single-window envelopes are set up for automated or manual addressing so you can feed batches through printers or place addresses in one pass. The extra-large poly window lines up with standard document templates, eliminating the need to fold differently or hand-label each piece.

• Large 4-1/2 x 1-1/8" window for visible addresses and statements
• Window positioned 7/8" from left and 1/2" from bottom for easy template alignment
• Compatible with common laser and inkjet printing workflows
• 500-count pack minimizes frequent restocking during campaigns

Are these envelopes secure enough for sensitive documents?

Yes — the interiors have a printed security wave pattern that makes text and numbers difficult to read through the envelope, while the durable paper stock reduces translucency. This helps protect account numbers, personal data, and other sensitive information in routine mailings.

• Security tint interior blocks visibility of document contents
• Heavyweight paper reduces see-through risk compared with thin envelopes
• Window material is clear but sized to reveal only address fields
• Designed for legal and business correspondence without extra wrapping

How reliable is the seal and what makes it quick to use?

The envelopes use an ultra-strong peel-and-seal adhesive strip that bonds across the flap for a secure closure without licking or moisture. The quick-seal design is made to handle thicker folded documents and repeated handling during mailing and distribution.

• Strong, fast-acting adhesive for consistent seals across the flap
• Peel-and-seal convenience speeds up preparation of large runs
• Seal resists tearing during transit and handling
• Works well with folded invoices, statements, and multi-page inserts

What size and quantity should I expect in a pack?

Each Aimoh pack contains 500 letter-size #10 envelopes measuring 4-1/8 x 9-1/2 inches — a standard size for business mailings. The pack is aimed at companies and departments that mail frequently and want to reduce supply interruptions while keeping per-envelope cost down.

• 500 envelopes per pack — ideal for regular office use
• Standard #10 dimensions fit common business documents and forms
