    ... for - but a "jiffy bag" is not the best medium to use without any form of internal stiffeners ...
  

*by Z***A on Reviewed in the United Kingdom on 6 February 2017*

Mine arrived crushed flat in the post but luckily the tube had not burst and so it was still able to do the job it was intended for - but a "jiffy bag" is not the best medium to use without any form of internal stiffeners ( such as a piece of cardboard) as the tube could have easily burst and caused some considerable problems with the post office automated sorting machinery.
