I love the design and think it looks great. However, and I'm going to say this cautiously, and don't wish to offend...there's a typo on the large leaflet - essentials is misspelled. You may be aware of this - I'm only mentioning it because it sounds like this event is a great opportunity for you to widen the awareness of your brand, and you'll want to seem as professional as possible.
I hope you don't mind my bringing it up - if it was me (if I could make soaps nice enough to sell :wink: ) there's a good chance that I would decide that it didn't matter, and use it anyway - I just wanted you to be able to make that choice (which you may already have).
I hope the event goes well for you
