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.

My New Go-To for Gentle Everyday Care!
Color: White
I’ve been loving my Boka Classic Manual Toothbrush, it’s truly transformed my brushing routine! 🪥 The extra-soft, activated-charcoal-infused bristles feel so gentle yet effective, especially along the gumline. They clean thoroughly without scratching or irritating sensitive gums, which has made a noticeable difference in comfort and overall oral health.

Get Yourself A Bright White Smile
Can't belive how great this works. You can actually see the staining it removes when you expel to rinse. A bit messy to use all be it being a powder. The taste isn't bad. I believe this works better than the whitening stripe, which to me are difficult to use. Gentle on your gums and teeth. I do not recommend and do not believe the manufacture does either to use on a daily basis. A bit pricey but so are the whitening strips. For a bright white smile I recommend this product.

Easy to Use and No Bad Taste
I really like this whitening powder, it’s easy to use and fits nicely into my routine. It works well as an alternative to regular toothpaste, and the process feels simple and quick.
One of the best things is that there’s no bad taste. It has a mild, clean flavor that makes it comfortable to use daily, even if you’re sensitive to strong or overpowering mint products.
After using it consistently, it seems to be working my teeth look a bit brighter, and it feels gentle enough for sensitive teeth without causing discomfort.
Minor note: Since it’s a powder, it can feel a little different at first compared to traditional toothpaste, but it’s easy to get used to.
Overall, this is a convenient and gentle whitening option that’s easy to stick with. A great choice if you want something effective without harsh taste or sensitivity.

Whitens but not a pleasant taste.
Yes, it whitens teeth but is abrasive. Not sure how good it is for enamel, and it tastes terrible.
