Compressed gas is still on the prohibited items list…..
Ill check in the morning to see if we have a barcode for sending it, but personally I’d use an alternative. It also includes all aerosols.
This one amuses me ‘Electronic items containing any batteries exceeding 100Wh’ so all mobile phones then – which get sent all of the time!! Generally it seems that if you pay the extra for recorded or special delivery, the royal mail rule book gets forgotten about.
I’ve only once had someone look at the list when sending a parcel (without a look of indeferance) and say “yes” – and they were sending arrow shafts (no tips or flights) but still classed as a ‘wepon’….
