Do you happen to know where I can buy this lipstick?

This is the Rosy & Rosha lipstick I'm currently using after receiving it as a gift from an acquaintance. The color is No. 1 Rosy Beige.

I absolutely couldn't find it offline, so I don't know if it was discontinued.

I searched online and found reviews, but I couldn't find anywhere to buy it right now.

I have a warm skin tone, but it was hard to find a color that suited my face and lips as well as this lipstick.

I've already used it all up, with only the amount in the picture left. Now that I finish this lipstick, I'm not sure which lip product I should choose to use.

If any Unnie's Pouch members know where to buy this, please leave a comment.
