Those who like Crest toothpaste may not necessarily like Crest's toothbrush. Those who like to use a small brush head may not necessarily like a big brush head. .
The most important point is the high cost. The added value of commodities is too high. People can afford a 150W BMW, but they will never appreciate a toothpick for 5 yuan.
If you can only brush it a few times, it is definitely not cost-effective. If you brush for a long time, the attached toothpaste will be improved, at least it is a bit heavy to hold with the existing toothpaste. There is also that everyone's usage habits are different. . Some people can exchange one toothpaste for three toothbrushes, while others need to exchange two toothpastes for one toothbrush. .
Therefore, your product should be made decomposable, the toothpaste should be improved, or the brush head should be at least durable.
