Amazon Basics A9 Blank Mailing Envelopes

These white A9 envelopes measure 5-3/4 by 8-3/4 inches and come in a 100-count pack. The listed features specify 24-pound white woven paper and a peel-and-seal closure, so they suit buyers preparing a substantial batch without wanting to lick envelopes.
Best for: mailing wedding, birthday, or other event invitations, as well as folded letter-size sheets. The listing says they hold folded 8-1/2-by-11-inch paper. Choose this option for a straightforward white envelope in a larger pack.
Limitation: The listed option is white, so it is not the pick for shoppers seeking assorted colors or a kraft finish.
Columbian A9 Self-Seal Envelopes

Columbian’s 100 white envelopes are made from smooth 24-pound white wove paper. The self-sealing closure uses a peel-and-press design, and the product details identify the envelopes for half-fold greeting cards, 5-by-8-inch invitations, RSVPs, announcements, and photos.
Best for: buyers who want a white envelope for event stationery and photo mailing, with a no-moisture closure. It is a useful middle ground between everyday mail and invitations that need a clean, professional appearance.
Limitation: The listing describes a white paper option; choose another product if a colored or brown envelope is important.

Limitation: The brown finish is not appropriate for buyers who specifically need bright white envelopes.
Buying Guide: How To Choose A9 Greeting Card Envelopes
What size is an A9 envelope?
The products in this selection use the standard A9 dimensions of 5-3/4 by 8-3/4 inches. This size is commonly listed for 5-by-8-inch invitations and half-fold cards. Check the finished card’s dimensions before buying, especially if it is unusually thick or includes inserts.
Should you choose self-seal or peel-and-seal?
Self-sealing designs use an adhesive closure rather than requiring moisture. Product descriptions use terms such as self-seal, self-adhesive, and peel-and-press. If you are mailing many invitations, compare the closure details to find a method that fits your workflow. Follow the specific product instructions when closing each envelope.
Which paper color and quantity fit the job?
White envelopes work for a simple, coordinated mailing, while VANRA’s assorted colors add variety and Eupako’s brown option provides a different look. Compare pack sizes with your mailing list: the options here range from 40 to 150 envelopes. Buying a quantity close to the number of cards helps avoid unnecessary extras or running short.
Can you print addresses on A9 envelopes?
Desktop Publishing Supplies specifically states that its envelopes can be printed with inkjet or laser printers. For other products, the supplied details do not confirm printer compatibility. Check the product information and your printer’s envelope setup before printing a full batch.
