Must have for chapped/dry lips
Unfortunately for me, my lips dry easily. Wearing myotape (mouth tape) at night reduces how often my lips get chapped and peel. However, my lips still need regular care. I have been using chapstick that doesn't contain standard endocrine disruptors, petrochemicals, and artificial dyes for years. Since there's concern about the high omega 6 content (and possible inflammatory repurcussions) of using chapsticks that contain sunflower seed oil, etc. In them, I decided to try beef tallow.
Most beef tallows come in tins and must be applied by hand, and then the hands must be washed. This product gives you the ability to apply beef tallow to your lips without having to directly apply your fingers to your lips. This is a must have!

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
