The seller (Abbie) is VERY responsive to any question that you send over email. The product itself is wonderful. Not only are the drinks creative and seasonally appropriate, the extras that they give (napkins, straws etc) make their way to my drink counter even long after the actual drink ingredients are gone.
The box contains enough ingredient for 4 servings, but I usually find that you can buy the soda water in an artisanal store and make more servings afterwards, because the bitters / syrups / extracts that they give are enough for far more than 4 servings.
I have only received one box so far but it's a great escape puzzle box. I went to facebook group to find out about past boxes and so far the comments have been great. Can't wait to receive the future boxes!!
