What soap boxes should I use?

[Servant4Christ]

I have an order for soaps that will be used in gift baskets for Christmas. This customer prefers boxes with labels. My question is should I use kraft boxes without a window, kraft boxes with a window, or kraft boxes with an open window? This will just be for plain unscented, uncolored ZNSC that I've been making for over 2 years now but I've never used soap boxes. Will the soap sweat inside the boxes or will they be ok? I'm so nervous. I've only ever sold to family before and this is one of DH's business clients that he gifted a bar of soap to a couple months ago.
