You can see at a glance that this is an advertisement for a toothbrush. Be sure to put it in your mouth in the morning and evening and let it rampage in your mouth. When you rub it, a big lump of white foam comes out (it will be lovely pink if the gums bleed) and it is stuck in your throat. If you have pharyngitis, it is even more unfortunate, and you have to endure severe retching. By the way, if you brush your teeth carefully, you may be late. You can't use this as an excuse to be late.

Toothbrush is a little devil, right?

However, all the evil it does is to protect its teeth. Get rid of the bacteria that want to nest in the teeth, clean up the yellow spots on the enamel, and change the bad breath when you get up in the morning.

You know, people who don't brush their teeth are so scary. No, it's disgusting.

Don't believe it? Look at those who haven't seen this advertisement.

Toothbrush toothbrush, I want to be friends with you!

PS: I don't know what an attachment is. Is this an attachment? I can explain it and help you supplement it.
