Not bad for the price point.
Scent: Unscented, Size: 8 Ounce (Pack of 1)
I don't mind this product; it's well-priced; however, in practice, it was slightly too oily. I prefer other beef tallow products, or even just straight-up beef tallow, rather than this product. Because I have severe eczema on my hands, I prefer tallow blends that have faster absorption. However, this product is perfectly suited for use as a night moisturizer or as a hand mask. I would probably buy this again if the formulation were less oily/greasy next time.

Exactly what I wanted and more
Scent: Unscented, Size: 8 Ounce (Pack of 1)
No odor, slightly greasy but thats to be expected. I apply it on my face before bed. I live in a dry desert so this is amazing for my skin. Within a couple days my skin looked glowly and hydrated. I even feel like my very fine lines are less noticeable (I'm only 27). My husband even commented how good my skin looks and he has no idea I even switched face moisturizer. I have sensitive and dry skin so I am very pleased. I wake up feeling great with this product. It's a heavy balm but I expected that so I really don't mind.

Not sure
Scent: Unscented, Size: 8 Ounce (Pack of 1)
Initially it has a very greasy feeling and takes quite a long time to absorb. Once absorbed it feels very nice. It is a very nice thick tallow, quality seems very good.

Moisturizing
Scent: Unscented, Size: 8 Ounce (Pack of 1)
A little goes a very long way with this product. It feels amazing and makes my skin so soft. It pairs well with my snail mucin. My skin looks beautiful. Just be careful not to use too much copilot said it can cause breakouts but I’ve been using it every other day for a week now with no break outs. I also pair it with a beef tallow serum.
