Large Letter Rigid Envelopes

Large Letter Rigid Envelopes from ColomPac provide the strongest cardboard mailing solution on the market whilst keeping you within the Royal Mail size constraints. Manufactured from extra strong corrugated cardboard to give your items the best possible protection during transit, these large letter rigid envelopes can even be used for sending slightly thicker items due to their expandable depth of up to 40mm which gives a snug fit. Our range of large letter rigid envelopes are just about as eco friendly as they come; fully recyclable, biodegradable, made climate neutrally and from sustainable materials. Available in 8 sizes, all come with a peel and seal adhesive strip closure for a secure seal, and a tear open strip for frustration free opening.

Please note: Large Letter sizing is up to 353 x 250 x 25mm with a 750g weight limit.
