Bull Brand Rolling Machine: The Bull Brand Classic Plastic Rolling Machine is probably the most popular rolling machine in our retail outlets and now comes in this new adjustable style so you can swap between 5 & 6mm filter tips at the flick of a lever. In the same was as the classic this the combi has a good sturdy body and the rollers aren't as restrictive as some rolling machines. The main advantage comes when you inspect the rubber blind. It is much more subtle, which means it doesn't fling your tobacco all over the shag pile and it lasts a lot longer than other brands. No blind will last for ever but this is about as good as it gets without sacrificing on value and effectiveness.
