I recommend Super Hard Hair Gel.

I received this as a gift and tried it for the first time. The capacity is quite large, and the price is very affordable. Selling three for around 10,000 won is an incredible bargain. The hold is high enough to set the hair strongly, and it is moisturizing. It even has a treatment effect, so my hair is shiny and bouncy. It gives a nice natural finish that makes my hair look beautiful. Since the quantity is large, I can use it generously without worry. The scent is nice, and the hold is strong.
