Yes, this is a complete replacement set designed to restore the original leak-proof seal of your mug. It includes the necessary components to ensure your lid closes securely and prevents spills.

Installation is straightforward and requires no tools. Simply remove the old, worn-out stopper and press the new one firmly into place until it is seated correctly.

Using genuine Zojirushi parts ensures the exact fit and material quality required for your specific mug model. Generic alternatives often fail to create a perfect seal, which can lead to leaks or compromised temperature retention.
