JAM PAPER 9.5 x 12.5 Open End Catalog Envelopes - White 250/Box

In this review of the JAM PAPER 9.5 x 12.5 open end catalog envelopes, the bottom line is simple: these are a reliable, economical choice for anyone who needs sturdy white envelopes in bulk for larger documents and cards. Our review finds they excel at protecting flat items like greeting cards, announcements, and folded patterns thanks to their generous 9.5 by 12.5 in size and smooth paper finish, while the straight flap with gummed closure gives a traditional, secure seal for mailing and storage.

Key Features

• Size: The 9.5 x 12.5 in dimensions fit large cards, catalogs, and folded patterns without bending or excess bulk.
• Quantity: A 250 per pack supply works well for offices, small businesses, or heavy home use where several mailings are needed.
• Closure: The straight flap with gummed closure provides a classic, tamper-evident seal that stays shut during handling and transit.
• Finish: The smooth paper finish gives a neat appearance for professional mailings and makes writing or labeling easy.
• Color: Clean white color creates a neutral, professional look that suits announcements, invoices, and personal correspondence.

Who It's For

These envelopes are best for small businesses, crafters, event planners, and anyone sending greeting cards, catalogs, or flat work that needs a larger envelope size. The 250 count and sensible price point make them useful for recurring mailings, craft fairs, or seasonal campaigns.

Users who need padded protection for fragile items or who prefer self-seal convenience may want to look elsewhere; these are unpadded, gummed envelopes designed for paper items rather than bulky or breakable goods.
