BioRock. Crystal Natural Deodorant Stone - Unscented Plastic and Aluminum Free Salt Deodorant Stick for Women & Men Eco-Friendly, Sustainable, Zero Waste 4.25 oz

I have been using the salt crystal deodorant that comes in a plastic twist-up tube for many years. I'm so glad to find one that uses the same salt crystal, in the same format (long rounded bullet shape, easy to apply to pits, as opposed to some that are square blocks), and with a non-plastic holder. You can use the salt without a holder, but it's just nicer with one. The cork holder fits the salt crystal perfectly, it's easy to insert and remove to replace, and the cork feels warm and nice in the hand, like a luxury product. And the salt crystal itself lasts forever---while I just bought this one, I've gotten 2+ years of use out of a single crystal of the same shape/size in other brands. So I expect this will last a long time too. Luxury feel + it works + extreme low cost due to longevity = the perfect deodorant.Also if you did not know, if you ever want to get rid of the cork holder, cork is recyclable! Take it to your local beer/wine store (like Total Wine) and look for a cork recycling station, often a tall box near the entrance. I think the used corks get shipped off and turned into shoe materials. Great to be able to buy a product that has a chance at not just going into a landfill!

I've probably tried a dozen natural deodorants and this one is by far the best! I've had it for a little over a month now and I'm not going back! It worked almost immediately for me; there was little to no acclimating time. And I love that the entire thing is compostable. There's no scent besides a slight salt smell. Some really sweaty days I have to apply twice but for the most part it's lasted 24 hours for me. The only problem I ran into is I went on a road trip with it and kept putting it in my toiletry bag after using (you have to wet it) and the moisture from the enclosed space caused some mold to form at the base of the cork. So just make sure you air it out before packing it away. It's definitely going to last a year, if not more so it even helps save some money in the long run! Highly highly recommend product. Even my boyfriend likes it!

These crystal deodorants do work (best if applied when still damp from shower) and I do not regret buying this product because I already know I like this type of deodorant, and it will get used. My only complaint about the BioRock one is that it is $14 for only a 4.5oz rock. It seems like most of the cost is going towards the cork packaging, which is unfortunately not as good as I'd hoped. I like that the cork is eco friendly and not plastic, but it is very loose, flimsy, and the crystal slips out of it. It makes more sense to just buy an already loose crystal deodorant, which I can get for $6 from a local business. I will probably end up only using the cork packaging as a travel case for my crystal deodorant, and I hope that it will hold up to that. That being said, I would still recommend this product as the deodorant itself is affective. Also, to anyone who may be confused about it, this product DOES contain aluminum, it is not aluminum free as some people seem to think. It is literally pure potassium alum, which is aluminum, so keep this in mind when purchasing it. I like this type of deodorant for several reasons (solid, long lasting, minimal waste, it works), but it being aluminum free is not one of them.

The best deodorant available. It totally works. It doesn’t stain clothes and last a very long time!! Great product guys!!!

I'm amazed at this... even the packaging is great. It's got a good, clean, "barely-there" scent, doesn't bother my skin, and (nice surprise) doesn't stain my shirts either. For years my go-to deodorant was Mitchum Unscented (which is a clear gel), but this Biorock has now won first place. The Biorock is at least as compact, has no plastic in the casing (instead, just a really cool, simple cork capsule), is solid (so probably isn't going to freak out the TSA), and it doesn't build up in my shirt fibers over time the way gel deodorants do. It's not perfect -- Mitchum goes on faster when dry (moist, clean skin is better for the Biorock) and Mitchum lasts 48-hours (need to use the Biorock daily), but these small downsides are far outweighed by all the advantages above. Plus, even though I'm no longer throwing away shirts just because the gel sticks to them forever nor polluting the environment with giant chunks of hollow plastic, I still smell good.

Seems like a great product. Lasts a long time. Well made. But causes irritating armpit rash. Discontinued using.

It’s great as deodorant. Scent free (truly, smells like absolutely nothing), and once you get over the weirdness of wetting your deodorant to put it on it’s perfect. But the cork container swells over time as it ages/you get it wet invariably. I’m only about 1/4 through the salt now, but the two halves of the cork won’t stay together anymore, and the salt is loose in the base. I’ve already dropped the salt piece once putting it on which shattered a corner off. Not ideal but I really appreciate how environmentally friendly it is otherwise.

I really like the sustainability and the product. My only change would be the cork is somewhat flimsy; cork can be more solid and structured . I feel like it could break easy
