The Combi straw & cup mug with a capacity of 240ml features easy-to-use handles and a silicone straw. I only used it once to prepare formula. The straw is unused, but I washed it once. Please refrain from purchasing if you are concerned about the condition. - Brand: Combi - Model Name: Straw Mug Cup Mug 2025 Model - Color: White/Blue Bear - Material: Plastic Made in Japan mug series, suitable for babies around 4 months old. Perfect for their mug debut! Set includes a first straw (4 months+), a first cup (5 months+), and a 240ml bottle. Sterilization by boiling, microwave, and chemical solution is OK. Dishwasher safe. W-Rakupita structure: Just tighten it to the mark! The cap also closes tightly to prevent leaks with a double seal. The drinking spout and packing are integrated, making it easy to wash and care for.
