For the purist, seekers of clarity. Made from fully tempered soda lime glass, the KeepCup Brew Cork Edition features a natural cork band. Made in Portugal using waste product from the wine cork manufacture, the band is beautiful to hold. Over time its patina will tell the story of your use. We recommend that you do not remove the band, even for washing. Hand wash and let the band dry on the glass.   CARE INSTRUCTIONS - For best results hand wash only. - Lid off can be heated to 100C/ 212F degrees. - Made from toughened soda lime glass, not unbreakable, but surprisingly durable.   OTHERS Filter comes with a Cork band, Latte lid (pantone 7528c) and Soft Charcoal plug (pantone Black 7c). Due to the variation in the circumference of the blown glass, your lid is hand fitted to the glass and may not be compatible with other lids. This colour is available in 8oz (small) ONLY.   REPLACEMENT FOR... Disposable cups! According to research, approx. 2 million disposable coffee cups are currently sent to landfill sites in Ireland every day and we don't want you to be part of that dirty statistic!
