C4 White Board Backed Envelopes

C4 White Board Backed Envelopes are the perfect choice for sending A4 sized important documents or photographs through the post whilst ensuring they’re kept flat during transit.

A peel and seal adhesive strip closure makes packing fast and gives a strong and reliable seal with no need for additional adhesives. Our C4 white board backed envelopes are an eco-friendly solution; completely plastic free, fully recyclable and biodegradable. Supplied in boxes for easy handling and neat storage.
