I ordered the Etude House Strawberry Curlers on Qoo10 (use the search function to search for the strawberry sponge curlers for best deals); and this is not the first set of curlers (will blog about the other two soon) that I have bought.
The curlers pack comes in 4 big strawberry (cute!) sponges. There is opening in the body where you wrap your hair in. These sponge curlers are more suitable to achieve large curls, and really focus on the lower portion of your hair – Korean style.
