This is a Japanese-made sterilizing case for baby bottles that allows for easy disinfection in the microwave with water. I've only used it about 3-4 times, so I think it's in good condition. I've been sterilizing using boiling water, and I'm selling it because I no longer need it. Since my baby only drank from the 母乳実感 (Bonyu Jitsukan) bottles, I'm also including a slim-type baby bottle (200ml) that I didn't use much. As a bonus, please discard these if you don't need them. I'll also include the nipples just in case. I believe I purchased the Jokin Jo-zu (sterilizing case) around March of Reiwa 7 (2025). I bought the baby bottle around January, and I used it for less than a month. - Brand: Combi - Color: Cream and Brown - Function: Sterilizes in the microwave with water - Made in: Japan - Suitable for: Baby bottles Thank you for looking. I will ship it in a box and then in a paper bag. The box has some creases.
