I bought this but haven't had a chance to use it, so I'm selling it. Instant purchase is OK. This is a perfect cup for practicing drinking from a cup, and it won't spill even if turned upside down. You can drink it like a regular cup because the liquid only comes out where you put your lips, but it doesn't spill. You can drink from anywhere on the rim of the cup, and it's unlikely to spill. It's convenient for going out and comes with a hygienic lid. ● How to use 1. Attach the packing to the cup and rotate the lid to secure it firmly. 2. Place the valve on top of the lid, and firmly press down on the heart mark in the center to secure it. 3. While tilting the bottle, you can drink by sucking on the edge of the valve. 4. When carrying, attach the cap to the lid that secures the valve. ● Target age: 6 months and up ● Capacity: 207ml ● Materials: BPA-free ・Cap: Polyethylene ・Valve: Silicone rubber ・Lid: Polypropylene ・Packing: Silicone rubber ・Cup: Polypropylene ● Cleaning instructions ・Pull the heart mark in the center of the valve and remove the valve, then disassemble the lid and bottle. ※ If the valve is difficult to remove, hold the bottle firmly and remove the valve by inserting your finger into the edge of the valve and pulling. ※ When removing the valve from the lid, be careful as the remaining liquid between the valve and the lid may splash. ・After use, wash each part with a mild detergent and dry thoroughly. ・Do not use nylon brushes, metal scrubbers, or abrasive cleansers as they may scratch the product.
