Awful flavour

Paper thin flavouring at best

the flavour seems to be less than before

Crispiness6%+0.26

not crisp at all

my only nag is that a few of the packets in the batch must have got air in them as the seaweed sheets were a soft texture rather than a crisp bite

Only thing is once opened they can lose their crispness hence one star less
