The new flex rods are simply amazing! No adhesive is necessary to stick to the eyelids. This saves you time and puts more money in your pocket. Still in the signature vibrant orange color. The color orange radiates warmth and happiness, combining the physical energy and stimulation of red but with the cheerfulness of yellow. Eye catching is the word that comes to mind and makes your before and after photos stand out! This combo pack includes 4 sizes (S, M, L, XL). They actually come in right and left so pay close attention to this new feature for the most precise fit ever.
