Big Joe Bean Refill 1 Pack Polystyrene Beans for Bean Bags or Crafts, 100 Liters per Bag

Used these Styrofoam beads as filling for an insulated cooking bag I use for camping and saving energy in an emergency. They work well and don't seem to smash down. I made a funnel out of a cardboard cereal box and poured the beads through it to get them into the bag. It was still messy, but the easiest way I came up with. I recommend doing the filling outside.

I was going to throw my son's beanbag chair away because it was very flat. He had it for about a year instead I found the beans to fill online. I was able to fill his whole chair up with only a half a bag great price and I still have a half a bag to use for when he gets low
