Activated Charcoal Toothbrushes Soft BPA Free, Made in Japan, Manual Toothbrushes with Wheat Straw Handle and Binchotan Bristles - Soft, Ultrafine, Tapered. Compact Head and Slim Design (4 pack)

I like these because they're small but durable with soft bristles. I've set up some comparative photo images to show their smaller and ergonomic size profile compared to other typical toothbrushes (including an electric one).For size comparisons:the small Oral B electric toothbrush shown is 1/2" diameter round head. The chunkier Colgate brand toothbrush head shown is 1 1/4" long & 5/8" wide; with taller, stiffer, mixed bristles. The Allentian charcoal infused brushhead: 1/2" width, 1" length, oval-shaped with uniform 1/2" long bristles that look & feel like soft nylon bristles.So the Allentian brushes are more stream-lined and sleek.You can also compare durability over time & use in the photos:Pink = brand new, unused brushOff-White = used about 10 timesGreen = used once everyday for about 2 monthsNo bristles falling out. Feels silky smooth in hand & on your tongue & lips. Bristles are very gentle on gumline, but firm enough to brush your tongue clean.Can't say much about the charcoal effectiveness... hard to gauge that, but our family only uses fluoride-free toothpaste, brushes daily, and no one has had any cavities for over 20 years. We have only begun using these charcoal-infused brushes for a few months, though. They're much neater than using loose charcoal powder obviously. I didn't really get them for the charcoal aspect as much as for the design, though. The charcoal is just a bonus.I would definitely recommend these for even toddlers to use (just make sure they don't chew on the bristles so they last longer). The handles have a nice tapered shape that is larger at the end to hold with some contours for grip.Attractive, soft color varieties that even my 18 year old son was fine with. The speckles add an attractive touch. Nice they come in 4 different colors (blue, green, pink, natural) to tell them apart.These can also fit inside travel toothbrush holders or on an old-fashioned wall-mounted toothbrush hanger, unlike many of those new-fangled chunky toothbrush styles, so worth considering for space-saving ideas.I also like that they're apparently made from natural materials (wheat straw), which hopefully is processed in a nontoxic way. I don't know how.I bought bamboo toothbrushes before these. They were fine except they started to feel rough on my lips, which is why I went to these, and I really like how smooth they are. Will definitely order more & recommend for anyone to use.

Toothbrushes are a lot smaller than I imagined they would be, but that wasn't an issue for me. The bristles have charcoal in them, but not enough charcoal to just brush with the toothbrush alone. I used some additional charcoal toothpaste with the brushes. The bristles are soft and the head of the toothbrush is comfortable enough to not feel weird when brushing your whole mouth. Small enough to brush with your mouth closed and still not feel uncomfortable.The brushes don't seem to fit well in any standard toothbrush holder, so I had to opt to place it in a travel tube instead.Serves its purpose and a good buy for what it is.

I like these toothbrushes. They are small and reach my wisdom teeth better than my Sonicare does. They are infused with charcoal--so you have to use a charcoal-based paste if you want the full effect. These are simple, have beautiful pastel colors, and work just fine. I did lose a few bristles the first time I used it, but other than that it is great.

Bristles are very soft and the handle is super easy to hold - this is a great toothbrush for someone who has wrist or hand issues. I have a variety of issues including focal dystonia and carpal tunnel and this is a toothbrush that is easy to use and doesn't hurt my hand to hold.

fantastic product, I love the fact they help keep bacteria in the mouth down. I have crohns disease and its important for me to keep my whole intestinal tract healthy, and that starts with the mouth. not to mention they clean my teeth better than ANY toothbrush I have ever owned, and I have owned a lot. top quality product and it will be a regular in my household forever.

I have very sensitive teeth and these brushes are wonderful! Very soft. The small head makes it easy to reach in all places in your mouth that a bulky toothbrush is usually too big for. My mouth feels very clean. I also purchased Hello oral care sensitivity relief toothpaste and it's the best toothpaste I've ever used (in case anyone was interested) I've only tried one, the soothing mint and coconut oil. Highly suggest

Only thing that is good about these is that work. It's a toothbrush. But I hated being lied to in the face. Toothbrush doesn't have any charcoal as far as I can tell(No bitter taste) and my biggest gripe is they are NOT made in Japan. They cleverly placed the amazon sticker on top of the packaging to make it look like it was made in Japan. Under the sticker it says, "Made in P.R.C", which is another way of saying made in China. The packaging marketing text on the front and back is in Japanese but it sure wasn't made there.Other than that the toothbrushes do have tapered bristles and it works. Great for my small jaw and getting behind my back molars. Just unhappy a company has to be so deceitful in order to sell a product. I'm just using them so the money isn't wasted.

The bristles are nice and soft, just what I wanted for my child to use. But they seem to come out of the brush head easily. They don't fully fall out, about 20 are just about halfway out but I can't seem to pull them all the way out. The handle is nice and slender, perfect for little mouths like kids. Just concerned about the bristles being swallowed.
