Best cotton rounds

I absolutely love this product! These do not fall apart while using. They are absorbent and excellent quality. Definitely worth the price. I have bout this twice already and I will continue to purchase these!!!

Lint free, strong, not super absorbent
Size: 100 Count (Pack of 12), Set name: Classic
These are my preferred cotton rounds. I use them twice daily with micellar water to clean my face.
There’s no lint, ever, unlike what I grabbed when I ran out once from the drugstore. The edges aren’t pressed to the point they’re abrasive, which I’ve encountered in other brands and is very frustrating.
They’re just the right amount of thick - easy to fold to a corner for running along my lower lash line to get makeup off fully, but not so thin they fall apart as you use them.
Both sides are equally soft and durable, and using one side doesn’t compromise the integrity of the other. Once one side is dirty, just flip it over!
I ordered the bulk pack to drop the cost per round to $0.02/per, since I know I love these and will go through them constantly. This is a great value.
I’ve used the same brand’s organic rounds, which are comparable in quality, thickness, softness, and durability, so if organic matters to you but you’re dubious that the cost could be so close while not sacrificing quality, you can be confident that Cliganic isn’t guilty of shrinkflation to cut costs on what should be a comparable yet more eco-premium experience.
Thanks, Cliganic, for making a perfect product!

Great Clean Alternative to Traditional Mouthwash, LOVE this!!
Flavor Name: Mint, Size: 3.5 Ounce (Pack of 1)
I’ve been really impressed with these Boka mouthwash tablets. They’re fluoride‑free and alcohol‑free, which is exactly what I was looking for, and the hydroxyapatite is a nice bonus for supporting enamel without the harshness of traditional mouthwashes. The tablets dissolve easily, the flavor is refreshing without being overpowering, and there’s no burning sensation at all. Do NOT chew and swallow like I did the first time. Chew, get salva going and swish. My teeth never felt so clean!!!
I also love that they’re travel‑friendly and cut down on plastic waste compared to big bottles. My breath feels fresh, and my mouth feels clean without that chemical aftertaste. If you’re trying to switch to a cleaner, gentler oral‑care routine, these are a great option.

Tasty, effective, and helpful against thrush
Flavor Name: Citrus Mint, Size: 3.5 Ounce (Pack of 1)
This is a good plastic-free, portable form of mouthwash. Pop one or two tablets in your mouth, chew well, add a little water if your mouth is particularly dry (mine is), swish, and spit. That's it. They don't burn like regular mouthwash, and they leave a nice flavor that isn't overpowering and that lasts longer than other mouthwashes have for me. It's a balanced flavor, if that means anything to you - basically, my mouth somehow feels right afterwards.
I was skeptical about the claim that these improve the mouth microbiome, but they've virtually eliminated the thick white layer (presumably thrush) that I've been fighting to clear off my tongue forever. So, yeah, these are definitely a winner.

More like a mint candy than mouthwash.
Flavor Name: Mint, Size: 3.5 Ounce (Pack of 1)
Hard to describe this product. Does it work like your typical mouthwash? No. Does it leave your mouth feeling minty and fresh? Yes, to a certain extent. Would I consider this an alternative to mouthwash on a consistent basis? No, it's ok for traveling because it's easy to transport.
When you chew this tablet, it has the texture and feel of a traditional mint. It's chalky and breaks up easily.
