Handling Instructions Be careful when drinking hot beverages. Before handling, make sure the top and lid closure are properly closed. When carrying hot beverages or carbonated drinks, always open the drinking spout before removing the lid. This releases pressure and prevents liquid from overflowing. This product is suitable for all types of beverages. However, avoid shaking the product with liquid inside. Pressure may build up. This may affect the leak-proof performance, so let the drink settle before opening. Be careful when opening the lid and the pack. A small amount of liquid may splash out when pressure builds up. If you are concerned about shaken liquid, unlock and slowly rotate the pack to release the pressure before fully opening. To prevent injury, do not allow children to walk or run with the product. Small parts are removable and easy to swallow, so keep them out of the reach of children. Not suitable for microwave or oven use.
