A6/C6 Manila do not bend envelopes come in boxes of 250 envelopes and are ideal for A6 sized photos, certificates, marketing materials and similarly sized flat items - remember A6 is A5 folded in half or A4 folded in quarters. A rigid 1000 micron backing card provides a stiff support and tough 120gsm paper keeps the envelope in good condition in transit. These envelopes are also printed on the front with a “Please Do Not Bend Message” to promote good treatment in transit and ensure your items arrive without damage. Peel and self-seal closure makes board backed envelopes fast to pack and high quantity boxes help save space and protect the envelopes on their way to you.
