First, the price of these is around 5$, depending on the site where you'd get these but on Beautynetkorea they are $5.35 for 3g.
The color might look just like a warm brown when you look at it alone but here you'll see how much red it has and why it is called "Red bean".
While the pigment of Etude House and BBIA is pretty much the same, it's texture of BBIA's that i prefer. BBIA's is smoother. And you can get the color more pigmented than in the swatch shown.
Staying power? Great as well.
