洗濯表示のマーククイズ　家事をする主婦を応援するアプリ

I don't understand because the marks on the laundry are often similar!
Is there anyone?

It's okay to check every time you come across
It ’s better to see it anyway,

Because you can do that
Sometimes just playing for about 5 minutes
Gain knowledge

If you spend a few minutes every time you look up
If you use it for a while
Wouldn't it save a lot of time in total?
