Thank you for viewing. This is a set of the convenient milk formula maker "Chonyu Jo-zu" and the sterilizer "Jokin Jo-zu". Included: - Chonyu Jo-zu: Instruction manual and original box included. ※ Conductivity confirmed. - Jokin Jo-zu: No original box. The Chonyu Jo-zu was used for a total of about 1.5 years. There is limescale and burn marks on the heating plate (see images), but I think it can still be used. The Jokin Jo-zu was used for about half a year. There is limescale and minor scratches. Please purchase only if you understand that these are used items. I will wrap them in new bubble wrap and ship them in a cardboard box via anonymous delivery. ※ These items are only sold as a set, not individually.
