Seal for stainless steel insulating stopper - TEMPflask. Fits all models except Spirit TEMPflask 0.5 L. Our motto is that Carl Oscar’s products should be used as much and as often as possible. This means that they will be exposed to both tough conditions and a lot of wear and tear. Offering most parts of our products as spare parts is therefore very important for us. We believe that our customers of course should be able to replace a worn gasket or a lost cap and thus further extend the life of their product instead of throwing it away and buy a new one.
