500ml is a lot and you're skin will take you for it.
 

This is my first time using this toner. Its a great starter toner if you are just getting into skincare/Korean skincare. There is a lot of alcohol in it so be warned. Its got a strong alcohol smell to it. However I havent seen much of a difference in my pores. But with that said, my skin hasnt dried out from using this toner (I do use a separate moisturizing toner after) nor has it broken me out. The top is really handy as I just need to place a cotton pad on top and push down to get the toner out. With the large amount you get in this bottle, it will take months for me to go through it all so it's a pretty good deal. Just be aware of the alcohol percentage it has. 

A very cheap and effective toner

I am not sure if i see a difference in pore size after using this. But i do like it. Since this comes in a big bottle i have been using this generously.
