These Royal Mail C3 Special Delivery Thick Envelopes come in a pack of 6, brand new with tags. Manufactured by Royal Mail, these envelopes are designed for secure and reliable shipping. Perfect for businesses and individuals looking for a reliable mailing solution, these envelopes offer a sturdy and secure option for sending important documents and packages. These were purchased for my previous business & never used. They are still valid due to the barcodes & senders name box being cleared. They are not prepaid.
