Review (4/5): works well for oils
I am really surprised how cool this jade ball feels, without any added ice or products. It says to crush ice, but the bottle is really small, so cold water is totally fine. I think this works great with massage oil and essential oils, as long as you take care to make sure the lid is secure. It does leak a little when water is in there, maybe just the thickness of product. This is a nice addition to any skin care routine, or a great gift idea.
