This excellent dental floss has a pleasant mint flavor and cleans interdentally perfectly. It's soft and expands slightly during use, so it doesn't irritate your gums at all. The quality is excellent; the floss doesn't break or fray during use. It's very economical to use, and the length lasts a long time. I'll definitely order this product again.

Expanding floss

Verified Purchase

What happens when it's exposed to air? It expands surprisingly much. Even so, it still goes between teeth without any problem, and because it's soft and doesn't hurt when it touches the gums, it's actually quite easy to use. The mint scent is quite strong.

Silk material

Verified Purchase

Japanese pharmacies only sell plastic floss, so I bought this. It's a small size, but it lasts a long time. I don't really taste the peppermint; apparently it's better to use it before brushing, but I use it after. It's very comfortable to use. It's incredibly stretchy floss.

Verified Purchase

It's nice and good, not too wide or too thin. It fits comfortably between the teeth and doesn't bother them, but I wish they would change the packaging. I'm worried the cardboard box might get wet and damage the floss.

Great

Verified Purchase

The thread is quite thin when pulled, a little wider than an Oral B, but when cleaned it expands and cleans better. I liked it.

great

Verified Purchase

This is a great eco-friendly product! It's healthier and more natural than traditional dental floss, without the worry of PFAS. It's suitable for all ages, and the packaging is well-designed and eco-friendly. It even contains coconut oil for antibacterial properties. I'll definitely be buying this again!

The scent is amazing

Verified Purchase

The peppermint scent is stronger than I expected. The quality is good and it lasts a long time, making it more cost-effective than Japanese products! It's made with natural ingredients, so it's safe to use.

Expanding sponge floss. The mint scent is pleasant. Personally, I prefer something with a slightly stiffer thread, so I probably won't be buying it again. It removes dirt well without any problems. If you like fluffy floss, this is for you.

Nope

Verified Purchase

It's simple, I hated it. It wasn't "glide-free," which made it difficult to get between slightly closed teeth. It had a mesh-like effect that widened but left small threads regularly, or even got stuck between the teeth. Very dry. In short, it went straight in the bin.

This is the only thing I buy.

Verified Purchase

It's hard to find safe and reliable floss. This one is 100% silk and contains no additives. I've used other Radius products, but this one is a little tricky to get through if there aren't any gaps between your teeth. But once it does get through, it removes a lot of dirt. It's an essential product for daily oral care.
