I highly recommend purchasing this trial kit before anything else from this company, for 2 reasons. First, to try out the products. I absolutely fell in love with the body oil and will be purchasing a full-sized version of that. This is a very powerful scent and will not be appealing to everyone, however, so I really recommend smelling this oil first. I also enjoyed the facial oil - it works very well for gua sha - the slip is excellent, and I'll probably also be purchasing a full size of this oil too. The serum was just "ok" to me. I'm unsure if I need this item. Lastly, I didn't really love the cleanser. It didn't clean as well as my normal cleanser, so I'll skip that one. The second reason is that these bottles are are very high quality GLASS bottles and glass droppers, and are refillable. This makes them the perfect portable vessels for your products, especially for the ones where you've purchased the full-sized versions.
