Lovely product, low ROI
Size: 4.2 Fl Oz (Pack of 1)
The cream is lovely, not greasy, low odor, and beautifully hydrating. However, being quite the frugal customer, I cannot, in good conscientious, pay the cost per ounce.

Update: Chemical smell?
Edit: Something seems to be different with the current version. Why does "pure tallow, beeswax, and raw honey" smell (and taste!) like cheap perfume? Ick. Good luck getting that scent out of your brain. And what the heck is it? I don't know why they changed it but it unfortunately wasn't an improvement. It's too bad. It made a great foot balm. Pretty moisturizing and the size and form factor made it easy to apply. Hope it comes back the way it was. _______ This has great/safe ingredients. It's huge. And the company seems legit so I tried it. I've given it a go and it's okay but it seems like the proportions would need to be adjusted to be more of a balm. It's good… just a little too greasy. This feels more like I just put my tallow moisturizer on my lips instead. I get that from Fancy Farm and I guess I'm going to have to stock up on theirs if I don't find something else here that has that consistency. (And no seed oils!) Lip balm needs staying power or it just becomes a nuisance.

Finally, a non-toxic chapstick!
So I typically make my own products at home using beef tallow. But I was in dire need of chapstick, and just didn't have any time or energy to do it, so I came across this brand on Amazon and had to try. I love it! Not only is it HUGE, but it is unscented, it's glides on perfectly and my lips feel super moisturized for hours. As with all tallow products, you have to be super careful about letting this stuff sit in the heat. So if you were planning on keeping it in your purse or car, it'll definitely turn into a ooey gooey mess. I keep mine in my nightstand in an air-conditioned room, and even then it gets a bit too warm on our hot 103F Summer days. Nevertheless, I recommend to those who are looking for a non-toxic chapstick that super moisturizing.
