Amazing product
I have just purchased my 7th jar! I absolutely love this product...and its American made! It leaves my skin soft, radiant and glowing! I didn't tell anyone about using it and people started asking me what I was doing differently. I get complements about my youthful glow! This company makes an amazing product and I hope that it will always be available! I have friends and family members hooked on it now. My mom just dropped a stocking stuffer hint to me tonight for another jar!

Legit balm. Not whipped. Made in USA.
Legit tallow balm. Not whipped. I love this stuff. It's the only thing that soothes, softens, and relieves my dry skin in the winter. Also made in USA, which is a priority for me.

Great winter moisturizer! Not greasy & absorbs well!
I needed a moisturizer that would last in colder weather. My skin is oily/normal and works well with my other facial products. I strictly use The Ordinary products and add this at the end to seal in the moisture. Pretty surprised how quickly this absorbed in to my skin. Has no scent and melts quickly on finger tips. I use it on my face and heels of my feet. Honestly love this addition to my fall/winter skincare routine. A little goes a long way! I have been using for a month now with great results. Definitely a great buy!

Great product if you can actually use it
Of the 4 orders I've placed for this lotion, only 2 have come perfectly. One of them came leaking tallow out of the container and package, and then it's replacement arrived with the jar completely shattered. The tallow itself is so hydrating and smells great, but if the company itself needs to fix it's packaging.

May need to transfer to a different jar since the lids break
I am very happy with the product but a little bothered by the packaging. The lid is cracked and doesn't stay on. The fragrance isn't what I expected, but it is pleasant and a comforting smell.
