Nuk First Choice Clinic aims at sustainable production. The gasket geometry of the TPE teats and the smoothly structured screw ring are manufactured in an energy-saving way from one single piece of material. Moreover, the design allows for easy opening of the bottles. A soft part on the upper side of the teat takes the papilla incisiva, a sensitive nerve centre on roof of babies’ mouths, into consideration. The small container for colostrum features gradation down to 1 ml in the spherical base, significant for mothers in a psychological sense, and can be emptied residue-free by syringe.
