Hi, I saw both thread of yours. Any difference between the pure orange and the orange and white ones?

Good idea to stuff it into my gym shoes and badminton shoes? Am thinking that I could get my shoes to stink less if I could remove the sweat moisture after use, XDD

How long can it roughly last before I need to reactivate it? Instead of putting it into microwave to reactivate, would drying it under hot sun in a container do the trick as well? What's a safe sheet anyway?

Sorry for all the questions...;;
