Top coat and nail hardener

I don't get nail art, I mainly get pedicures.

I don't go to a shop to do this; I just stick stickers on haha.

But the sticker came off easily. (Near the little toenail)

So I went to Daiso, bought top coat and nail hardener, and tried sticking them on, and they don't fall off easily haha.

I applied nail hardener before attaching the stickers, let it dry, then applied the stickers, smoothed them out, and applied a top coat; it makes them really durable^^

The price is reasonable, and it's great that it protects my toenails^^

But is this the right way to use it? Hahaha. I'm not entirely sure if I'm using it correctly.
