Someone I know is working in that industry, so
I know a few hospitals for idols, but they never treat them well.
The prices are really evil.
Even if you give a discount to acquaintances, it's still expensive.
There were even places that made false advertisements. Among them, there was even a person who said he was going to retake the exam after losing his double.
I, too, am an idol. I had it done at a place that does it, but I have to go back to fill my nose with Megaderm.
