Purchased on Amazon in October 2025. Around 2000 yen for two. This was the easiest mug to use. I had two to reduce drying time. One is missing the straw component and is unusable. Richell Aqulea Mug with Straw Type R Suitable for babies around 6 months old. Capacity is 190mL (maximum scale capacity 150mL). Materials are polypropylene and silicone rubber. Dishwasher safe. Thank you for viewing.
