I bought 3 cartridges but they refused to give me the delivery, pretending they have no stock at all for more than 3 months.
The customer service kept asking me to order it through amazon which is twice more expensive.
Because this company is located in South Korea, I found their South Korea market.
The price was only $8.
I ordered 8 boxes and I got it delivered to my friend's house the next day.
Company name was the same, address was the same.
