ELI5: Silica Gel Packets

Some products (bags, cases, ...) come with those silica gel packets inside to control humidity. Should I leave them there while I use it? Is it bad for electronics or something else? Or is it used only while it is stocked in the store before selling?

They are there to absorb moisture in the packaging. To prevent misting during transport through different temperatures.
They won't help much after openning. Also they have a "capacity" for absorbtion, after a while they are useless.
