Great Gift
I'm not the best gift giver and I never know what to give my mom for Mother's Day. She always appreciates a new plant or flowers for her porch or yard. This year I wanted to change it up and this was a perfect addition to the flowers I got and will look great on her porch. It was securely packaged, very light weight.

Very fragile
I bought 2 of these and both broke. I wouldn’t suggest buying this. Only if it’s in a sheltered place.

Very healing
I bought this for face but had also heard that this can be used for other skin issues. Yesterday, I cut my index finger with a label remover (basically a razor blade). Once I stopped the bleeding, I kept it clean and covered for a bit. Before bed, I decided to put a dab of this on my cut, when I woke up this morning, it's like a miracle! It barely hurts and looks quite healed!
