Using these power popper refills is a breeze. Just open the carrying net and take out a refill. Insert it into your Hog Wild Power Popper or Squeeze Popper as per the toy's design. When playing, make sure to keep it away from small children who might put the refills in their mouths. For maintenance, store the refills in a dry place. Avoid exposing them to extreme heat or cold as it might affect their quality. And always remember, these refills only work with Hog Wild Power Poppers and Squeeze Poppers, so don't try to use them with other types of poppers.
