Founded less than 20 years ago, Na'vi is a very young oral care brand, relying on the development of soft rubber bristle antibacterial toothbrushes, its sales in 2015 were close to 300 million yuan, which can be described as rapid development.
 
Generally, oral care brands are mainly nylon toothbrushes, and a few are supplemented by TPU soft rubber bristles, while Navi's entire line is equipped with TPU soft rubber bristles, the bristles and brush heads are integrally formed, there is no hair planting pore size, and it is easy to clean between the brush filaments, and it is not easy to hide dirt and dirt. In addition, TPU bristles are not as easy to wear as nylon filaments, and they are soft and comfortable, and it is not easy to cause gum bleeding when brushing, but the elasticity of soft bristles is not as good as nylon bristles, and the tip diameter is difficult to reach the level of 0.01mm of nylon filaments, and the overall cleaning strength is weak.
 
Manifesto of Youth, Meilun and Meihuan are the three main series of Nami, and there is no significant difference in bristles. Different from the Youth Declaration series, Meilun and Meihuan series brush handles have soft rubber anti-slip, the brush handle is moderately thick, and the grip is better, however, the price of the Youth Declaration series is also relatively low, and the unit price is mostly below 10 yuan.
 
There are three main sizes of Normi brush heads: S, M and L, L is a common standard size brush head, S and M are relatively small, Meilun series is mostly standard L brush heads, and peaceful and power toothbrushes are L brush heads, with better power grip and slightly higher price, about 8 yuan a piece. There are many options for the size of the Meihuan series brush head, and the overall price is also higher, with a soft tip smooth and lady toothbrush with S brush head, which is flexible to use, and the price is 12.5 yuan and 15 yuan respectively.
 
Children's toothbrush series from 0 to 1 has won the iF Design Award, it will be divided into 1-3 years old baby teeth teething period, 2.5-6 years old baby teeth period, 5-10 years old tooth replacement period and 9 years old permanent teeth period four stages, the stage division is scientific and reasonable, size, brush handle design is targeted, carrots, cartoon dolls and other shapes of the brush handle is also full of cuteness. Relatively speaking, TPU soft rubber bristles are more comfortable to brush teeth, and children have a lower degree of resistance, but in terms of cleaning strength, you still need to use a nylon toothbrush to supplement brushing to thoroughly clean the mouth.
