I picked up this Nature Republic color correcting cushion on my latest trip to Seoul in December. I purchased it in a Nature Republic store in the Hongdae/홍대 area. It currently costs 18,900₩, but I believe I got it on sale for 15,000₩ thanks to the new product launch sale they had going on for this. (Note: Nature Republic sales promotions vary by store)
This cushion comes with three shades: pink, green, and purple. Each of these colors are meant for different purposes. The minty green is meant to cover redness, pink helps cover up dark under-eye circles, and purple helps balance yellow-y skin-tones.
I like the packaging of the box because it fits the feeling of Nature Republic with a natural-looking box and simple logo design. Most, or at least many, of Nature Republic's products are green, white, or a combination of the two, and this cushion is no exception.
