Di Mei is relatively expensive. I can't tell you exactly how many. I've done very simple nails before. It's not as complicated as you said, and it costs more than 90 yuan. Many friends will not choose to do it in Di Mei.
Go to Nishimiya, where it's cheaper. After bargaining, it is estimated that it will be settled around 30 yuan.
I know an old Nishinomiya boss, who revealed it in secret.
