Promotional Sagaform Nature carafe with cork stopper 1,5 liter This slender glass carafe from the Nature series features a dark brown cork ball and combines durability with flowing shapes and mystery. Sagaform loves cork because cork is the most durable of all organic materials and completely impervious to liquid. The shape of the carafe is wavy and harmonizes well with the cork ball. This carafe can be used as a white wine or water carafe.
