Like new. Opened but never used to store milk. Description from website: Simply pour your fresh milk into the molds that hold 1/2 ounce each. Create up to 64 half-ounce cubes using two layered trays for easy, on-demand use. Keep it in the freezer and store additional cubes in the lower compartment until needed. Take out only as many cubes as the baby needs for the feeding, and put them directly into the bottle (each cube pops out easily due to the silicone flexible bottom surface, and fits easily into either wide or narrow-neck baby bottles). Warm your baby bottle as you normally would (Try using your Chiller as a bottle warmer). Sit back with your baby—no garbage and no cleanup besides washing the bottle when you're done.
