Rizla have gone through all sort of changes over the years.
They used to use really shit pulped cardboard foe the back of the inside of the packet, this cardboard never rolled properly for roaches and would kinda fold in a triangular kind of fashion.
They they change that and started using the nice thin green card of a better quality, this rolls like charm.
The they started gluing the packs,why I will never know? There was never a problem when the packs weren't glued and it means that making roaches from the packet less efficient.
Then they started adding some stupid bit of piece of shit bit of advertizing paper, which you have demonstrated is total a waste of time.
I' sure there are many other things I haven't mentioned.
Luckily for me I no long roll joints and my tobacco days are behind me, preferring to vape instead!
