I received this as a gift from a friend, but I have never used it and it is unused. It does not come with a box and has been stored at home, so please understand this before purchasing. ☽ It can be used in 3 ways by switching between two types of lids! ・Straw mug ・Snack cup ・Direct drink cup You can use it at home to practice drinking with a straw, and once your child is used to drinking with a straw, you can remove the lid and use it as a cup! It can also be used as a snack cup when you go out. Point! Align the two round marks on the lid with the handles and fit them together. The lid will curve nicely and close securely. ◇Material BPA-free silicone Microwave, dishwasher, and boiling sterilization safe ◇Capacity 250ml (With markings inside the mug)
