The hard plastic dust cover for the SNES carts will not fit inside the box, so you can save them, sell them, whatever

These protectors are a strong yet pliable firm plastic that will protect the important things

I actually felt kinda silly loading my ugly, BTF carts into these nice shiny clear plastic protectors

Clear plastic, fold them yourself boxes to protect your carts because you're collecting/playing on a budget and cant afford to buy CIB units, or if you can, you aren't using them because OMGLABEL DAMAGE

BONUS!Not a full 5 stars because if you aren't careful while folding, it is possible to rip the plastic with your giant meat-hands, and if you're loading while otherwise distracted, you can get a fierce plastic paper-cut on the edges while folding or loading
