Like all nendoroid pouches it comes with foam for you to cut, so your nendoroid fits just right and doesn't slip. I bought this for my Victor nendoroid and he looks sooo cute in it. After cutting away the extra foam I then placed it on his sides, so the pouch would retain it's form on all sides. Was it a needed purcahse? No, but I certainly love it and don't regret buying it.
