Purchased in January 2025 and used initially. I received several sets of dishes as a baby shower gift, so I don't think I used these very often. Please check the photos. The bear plate is unused. Microwave and dishwasher safe. Boiling sterilization: Yes. Microwave sterilization: Yes. Chemical sterilization: Yes. Sodium hypochlorite solution: Yes. As a bonus, I'll include a set of 3 small, divided containers. These were used about 3 times. Would these be useful for storage? If you don't need them, please let me know in a comment or message after purchase! They are used but clean, so you can still use them! Please purchase only if you understand this.
