Hints and tips
Royal Mail: most C5 all board envelopes fall into Large Letter or Small Parcel categories depending on thickness and weight – check before posting.
Label application: use strong adhesive labels or marker pens, as glossy coated board may resist standard labels.
Storage: keep flat to maintain rigidity and avoid humidity, which can warp the board.
Customisation: ideal for overprinting with branding – company logos, return addresses and promotional messages.
