## Questions & Answers

**Q: These say 100% recycled, are they actually? They seem like any other envelope to me**
A: Yes it is

**Q: Are these 'small parcel' with royal mail? (small parcels are up to 35x45cm and these appear to be 45.7cm)**
A: No! Sorry to say I have been refused countless times with these for small parcels. I now have to trim them down. They used to be accepted and theyve now got stricter

**Q: how many sheets of A3 paper would fit in the A3 envelope? I need to send documents of up to 15 pages would they fit in one envelope?**
A: Yes
It will fit at least 20 sheets.

**Q: What are the dimendions of the backing board, and do you sell these seperately?**
A: The backing board is normally the same size as the envelope. If you want to buy the board separately use the word greyboard in the search engine

*by A***R on Reviewed in the United Kingdom on 22 February 2019*

I had been looking for a large 'Do not Bend' envelope for ages as I needed to send a print to Canada. Couldn't find one in a Post Office anywhere and as the newsagents on our high streets are all disappearing I was at a loss until finding these and I wasn't disappointed. Now I have a supply in case I need one again.
