Does exactly what it says on the tin!
They are still in the demijohn, so only time will tell how well that they have worked, but I don’t see any problems.
I’ve not actually used them yet, as the beer is still fermenting, but they seem fine.
Great value cider kits. I have made both the Apple and Pear a few times with very consistent results using either dextrose or liquid enhancer. An ideal kit range for experimenting with water and sweetness levels.
