I know this will sound silly, but everyone is talking about how hard it is to seal the bag. Sharp knives, credit cards etc etc
I’ve discovered all you have to do is flick the seal with your forefinger nail all along both sides and the stuck powder puffs out and hey presto the bag seals like a dream.
Hope this helps someone
Simple and effective, just how I like things.

Fold top of bag over two or three times. Put three clothes pegs on to clamp (or those office clip things). Job done.
