Very simple question, but I can't find the answer for it.
I don't quite understand when they say 3 months use, is it as in you can use them lets say 90 days and if you wear it for lets say 20 days you can still use them for 70 days no matter when, or is it 3 months is 3 months so if you don't wear it in that time it still goes to waste.
Sorry very hard to explain what I mean.
Thanks.
