🇵🇭 For Philippines customers
In the Philippines, Thermos JNL carry mugs are a daily companion for office workers, students, and parents who want their coffee, tea, or cold water to stay at temperature through Manila heat and long commutes. Over time the silicone gaskets wear out and the lid starts to leak.
This genuine B-004643 set lets owners restore that perfect seal at a fraction of the cost of a new bottle. It is the smart, value-for-money choice for practical Filipino households that trust authentic Japanese parts to keep their favorite Thermos mug working like new.
