a perfect manual toothbrush
Color: Mint
this is definitely my favorite toothbrush i've ever used. even though it's just a manual one, it's still my favorite. it's aesthetically pleasing and the bristles are perfectly soft so it doesn't hurt my gums (i naturally have sensitive and fragile gums). i love caps that covers bristles; it's a must if you keep your toothbrush in the bathroom and this toothbrush comes with a cap that clicks open instead of one that slides on and off, pretty unique and much more hygienic as it keeps the germs out much better.
i can't comment on the capabilities of the charcoal since i just received this but i can say that when i used it, i didn't feel any grit at all, so i believe boka's claim that the charcoal is soft enough to be safe for teeth (most of the time, charcoal is too gritty for teeth and ruins the enamel) the toothbrush is also pretty hefty so it's not cheap! paired with the boka toothpaste, my teeth feel so clean. now off to buy the whitening strips, floss, and mouthwash tablets from my new favorite brand!

Excellent toothbrushes!

I absolutely love these toothbrushes. They clean so well and there is just this perfect bristle hardness to it so that my teeth and gums feel like they’ve gone to the spa.

Super Soft & High Quality – Great Toothbrushes!
Color: Multi Color
Love these toothbrushes! The bristles are extra soft and comfortable, making them gentle on gums but still effective for cleaning. The overall quality is excellent, and they’re a solid pick for both adults and kids. Highly recommend for everyday brushing!

Lovely dense and soft.
Color: Multi Color
Perfect toothbrush.
I’ve always loved a super stiff toothbrush, it just felt right, like scrubbing the grime off. BUT, I ended up scrubbing my gums into recession. So I’ve had to buy soft toothbrushes.
For years I’ve hated them. Waterpik, floss then brush and the brushing felt always felt like I wasn’t doing anything. I disliked everything about the bristles.
These were bought on a whim, they’re pretty and have four which is how many I needed to replace everyone’s toothbrushes.
I LOVE these. They’re definitely soft, in a way I haven’t felt before and can’t really articulate, but they’re also dense. There are a lot of bristles. The bristles feel like I’m getting my teeth very clean, like they’re getting into all the little areas they need to.
The only issue I have is they squeak a little and that can be annoying.
