Our Zeal double-walled, insulated butter dish takes a standard 500g spreadable margarine tub or 1lb butter pack. Not only does it look great with a colour co-ordinated design, the contrasting inner compartment and lid keeps the butter at the perfect temperature and ready to use, making it ideal when baking. For softer spreads, once taken from the fridge the tub will keep the contents cooler for longer, so no more trips to the fridge between servings!
