Only paper items such as letters and documents should be sent inside regular paper envelopes.
Any other items could easily be damaged or lost in transit, and so shouldn’t be posted in regular paper envelopes. Some examples include:
- rigid or inflexible items like keys, pens, USB sticks or CDs, which could be damaged by our machines or torn from the envelope and lost
- bendable or crushable items such as photographs or certificates, which could easily be bent or creased
