It's presumably too late for this product iteration, but a zippable bag like the one that comes with a CB6000 is probably more practical than a box with foam. That way it'd be easier to transport and store. Most of the time foam ends up in the bin shortly after purchase.
I gotta say looks great! But yeah, perhaps you can include a zipper case in the back of the packaging or something. Or perhaps a notice that it fits perfectly into the CB cases. Looking great though! very xcited :D
