Very good for the skin
This sebum and honey balm is a jewel. It absorbs very quickly, leaves no greasy feeling and hydration lasts all day. I use it on my face and body. As it is 100% grass-fed, you can see the quality. Goodbye dry and tight skin. The 120g bottle yields a lot. I'm going to replace it

Made in China
I'm sorry but I would have never bought this item if I knew it was manufactured in China. They don't have the quality control we have in the U.S. and that's extremely important to me when using body products and taking supplements.

Elsie approved, no bull, bee sweet.
Smooth as warm butter, not at all greasy, absorbs faster than a sprinting calf, easy on one’s hide, no barnyard smell- more like a field of clover, leaves the skin udderly refreshed and glowing. It’s a honey of a deal and worth it. Silly comments, but all true in this gals opinion and that’s no bull.

Great product!
Style: Deep Moisturizing, Size: 1.76 Fl Oz (Pack of 1)
I love this stuff! My mom introduced this to me while I was visiting her, and within 3 days of using it I knew I needed to order one for myself. It has no smell, goes on buttery soft, and soaks in well. It is not heavy at all. At night I layer it on thicker and during the day I put a very thin layer on under my makeup. My skin is so much softer and hydrated. I have had small bumps on my cheeks for so long and they were gone within 3 days. My skin looks dewy and soft.
I read reviews of other brands that smelled, were oily, or too heavy. This is none of those things and it is a great price!

Best Beef Tallow Cream I’ve Tried
Style: Deep Moisturizing, Size: 1.76 Fl Oz (Pack of 1)
Exactly what i was looking for, some of the beef tallow creams have a weird consistency which i don’t love wearing during the day. This cream is perfect for day and night. smells very good, application is perfect not greasy, moisturizing, soft. I love it! 10/10,
will be buying again 💗
