10 x 13 Catalog Envelopes with Clasp Closure - Christmas Red 250/Box

In this review of the 10 x 13 catalog envelopes with clasp closure, the bottom line is simple: this pack is for anyone who needs bold, no-fold mailing or document storage during the holidays and wants an economical box quantity. The reviewer found the bright Christmas Red color makes contents stand out for seasonal mailings and internal filing, and the open-end 10 x 13 size holds standard documents flat without folding. For bulk needs like promotions, office organization, or mailing larger sheets, these envelopes deliver visual impact and convenience at a low per-envelope cost.

Key Features

• Size 10 x 13 in: Holds standard and slightly larger documents flat so papers arrive crease-free and ready to file.
• Clasp and gum closures: Includes a folding metal clasp plus a gummed flap option for added security and flexibility when sealing.
• 250 envelopes per box: A large bulk quantity that reduces repurchase frequency for offices and events with high volume mailing needs.
• Smooth 24lb paper: A smooth finish gives a professional look for marketing materials and internal distribution.
• Recycled content: Made from 30% recycled paper for a lower environmental impact compared with non-recycled options.

Who It's For

These envelopes suit small businesses, schools, and organizations preparing seasonal mailers, catalogs, or internal packets that need to be sent or stored without folding. The bold red is especially useful for holiday campaigns, donation receipts, or any context where immediate visual recognition matters.

Those who need very heavy-duty mail protection or thicker stock should look elsewhere, as some users noted the paper and clasps feel lighter than heavy industrial mailers. If extreme tear resistance or padded protection is required, opt for heavier card or bubble mailers instead.
