Finum Goldton Filters Given the delicate tissue structure that makes up the filter, the product may be used for fine teas and coffee alike. The combination of high quality plastic and stainless steel allow the user to have an aromatic enjoyable experience while the tea lid maintains the tea warmer for a longer period of time. Once the brew is complete, the lid can simply be flipped over and used as a drip tray for the used tea filter.
