Not for me
For me… it was way too greasy,spread on to my face around mouth. But worst of all it gave my lips a slight allergic reaction. I’m a fan of beef tallow I use it frequently but my normal tallow was not in stock so I tried this one. It wasn’t for me unfortunately.

Great product, delivery needs work
Good product, good smell, feels great. However, the tube is much too large -- like the diameter of a quarter. It's way too big to comfortably apply to your lips. I appreciate more product for the money, but I would have preferred a more usable (smaller) size.
