Kjaer Weis Lush Up Volumizing Mascara Refill is for use with the Kjaer Weis mascara metal case. This natural mascara is made from real ingredients and natural waxes for dense, fluffy lashes that are anything but fake. A specially engineered brush featuring dense, staggered bristles lifts and plumps the lashes while a tube with just the right amount of suction prevents clumpy application and excess product waste.
