In all honesty, if you wanted something similar it'd be easy to cut a piece of packaging foam to fit the beylauncher, grip, and possibly a few beyblades as well.
Made this little box to hold my grip and a beylauncher just by drawing around the items, and cutting out the shapes for each object with a stanley knife.
Just slot it in to a larger section of a hobby case that you can get for less than $10, and you've got a larger, better version of this.
