This is the 2nd different new style LFTs I've had recently through the post. The buffer solution is in the tube and the spout is attached to the tube and there's foil on it. The foil is so hard to remove!! I've had to throw one away already as I cant open it and resorted to stabbing another one with scissors. Anyone know if there's a knack to opening them? It's worse than the foil on the milk.
