I purchased this here. I'm selling it because my child learned to drink from a straw after using it 1-2 times. It will be shipped without the box. Please refrain from purchasing if you are looking for a perfect item, as it has been stored by a non-professional. Thank you. Learn natural lip movements and step up correctly. This mug allows you to practice drinking from a straw in two ways. You can change the mug parts, making the transition from straw practice to straw drinking and then to cup drinking smooth. ●Product Information● Product Name: Try Straw Lesson Mug SD Target Age: From around 5 months old Size: 11.5 x 7.5 x 12H (cm) Maximum Capacity: 200mL Materials: Polypropylene, Silicone rubber Dishwasher safe Boiling and chemical sterilization OK Retail Price: 1430 yen
