Naison Klin is the No. 1 brand of interdental brushes in Taiwan, and entered the mainland market in 1998. With the surge of e-commerce in mainland China, Nathan Klin has also kept up with this wave of trends, and in the 2018 FMCG sales ranking released by JD.com, Nathan Klin has become the biggest winner in the dental floss stick market.
 
Nesenklin mainly produces dental floss sticks, and there are fewer styles of dental floss rolls. The fine slip floss is the thinnest and the weakest cleaning power, and the slippery is slightly thicker than the fine slip type, and the cleanliness is also a little better. Both are made of polymer slip wire, which is very thin and has a relatively smooth sense of use. The difference is that the fine slippery dental floss stick is packaged separately, which is easy to carry out, and the price is more expensive, the reference price of a box of 50 pieces is 20 yuan, while the 60 pieces of slippery dental floss sticks are only 8.5 yuan.
 
The flat wire dental floss stick and the high-tensile flat wire dental floss bar body are made of polyester, which has good elasticity, is relatively tight under natural conditions, and has good cleaning strength. But the disadvantages are also obvious, it is not wear-resistant, easy to break the thread and fluff, this kind of dental floss is more suitable for people with large gaps. The flat wire floss stick has a wider body than the high-tensile model, and the cleaning strength is also the strongest, both types of dental floss are 50 pieces, and the price of a box ranges from 6-8 yuan.
 
Nessenklin's floss sticks are unscented, while the dental floss is mint-flavored. The thread body made of polymer slip wire is thin and round, which is easier to slide into the gap between the teeth, which is suitable for novices but has average cleaning strength. The reference price of 50 meters per box is 13 yuan.
