This review is for the "Holiday Spirit" kit. Each bottle was individually wrapped and arrived sealed. They were larger bottles than I expected - I may have not read the details close enough, but I was expecting 10ml bottles and received 15ml bottles. I opened each one and so far am pleased with the scents, as compared to another expensive essential oil brand I have also purchased. I haven't tried them in my diffuser yet, so I'm hopeful their scents will hold up!
