That set is still on its original box sold by DS. All the sets you see on the DS catalogue and have the regular set numbers, are all sold in their original box.
As it's an accessory part, yes it will be.
yeah i agree - they're on the add-ons catalog because their respective themes are discontinued and those 'leftovers' have to be in a 'sales section'i guess they use an add-on scenery to make them match with the rest of the pics...
