C4 Rigid Cardboard Gusset Envelopes [Qty 100] 229 x 324 x 25mm
C4 Rigid Cardboard Gusset Envelopes to fit A4 brochures. Internal dimensions are 229mm x 324mm with a 25mm expanding gusset to allow for bulkier contents.
These Rigid Cardboard Envelopes are made from strong 400gsm card in natural Manilla brown colourway. Sometimes known as Capacity Book Mailers, they are designed to post items such as brochures, books, DVD's etc. that need that extra depth to fit, plus protection from a strong card material.
Price is for a box of 100 x Rigid Card Mailers
*Please note that the effective size of the envelope decreases dependent on the thickness of the item inside (e.g a 20mm thick book will decrease the effective size of the envelope more than a 5mm thick brochure). If you are uncertain as to whether contents will fit this envelope, we recommend ordering a FREE SAMPLE (click 'request a free sample' button above)
