Great product!
This is great lip balm, coming from someone who can't be without something on my lips. My only wish is that they would make it in smaller tubes because this one doesn't fit into pant pockets as easily because it is larger in size.

Worth it
These chap sticks are absolutely massive, it’s so soothing to chapped lips and I’m sure they will last a while. The texture is creamy and light on the skin. I’ll definitely be ordering more down the road

All it claims to be!
This product is all it claims to be!! Very smooth, buttery and hydrating. I do not enjoy the vanilla scented one. It has cinnamon in it which I was not expecting based on the description. If it was plain vanilla, I would definitely enjoy it more. I will probably buy the honey one over any of these other scents.
