Product Identity

Columbian COLO403 envelopes are 6 x 9 inch catalog envelopes sold in a 30 pack. They suit home, office or school users who need a modest quantity of peel-and-seal mailers for everyday correspondence.

Self-Seal Closure

The Release & Seal strip removes the need for moisture; peel the protective paper and press to close. The adhesive stays dust-free in storage so each envelope remains ready to use whenever you reach for one.

Durability Under Load

Heavyweight 28 lb brown kraft paper resists tearing when fully loaded with folded documents or greeting cards up to 5.5 x 8.5 inches. The center-seam, top-loading design keeps contents secure during repeated handling and transit.

Questions about this item

How much space does the 9.13 by 6.13 inch envelope leave for a 5.5 by 8.5 inch greeting card?

The envelope is slightly larger than the card, giving a small margin on each side so the card slides in and stays flat during mailing.

What does the self‑seal closure mean for everyday mailing?

Pull the paper strip to expose the adhesive, press the flap down, and the envelope seals without any moisture or sponge needed.

Will the 6.13 inch height fit in a standard letter tray or desktop sorter?

At 6.13 inches tall and only 0.1 inch thick, the envelope sits easily in most letter trays, desk organisers and file pockets.
