🇺🇸 For US customers
For American homeowners, renters, and parents looking for practical, well-made everyday items. Thermos mugs are everyday companions for office workers, students and parents who carry coffee, water or juice on long commutes. Over time the rubber seals wear out, and a worn gasket means leaks inside bags and lost insulation. This genuine silicone packing set lets owners refresh their JNR mug at home for a fraction of the cost of a replacement bottle.
American buyers value authentic Japanese parts that fit perfectly and last. With matching lid and stopper gaskets sized for JNR-350 through JNR-750, this set is the practical, money-saving choice for anyone who wants their trusted Thermos to seal tight and pour clean again.
