The handless glass brewer is an elegant glass coffee maker, in a one-piece hourglass shaped vessel made of high quality, heat resistant glass. It comes with a stainless steel filter if you do not want to use a dripper and filter paper. The collar serves as an insulated handle around the middle of the coffeemaker. The 2 to 3 cups glass brewer is perfect in size for home and office usage. The brewer's borosilicate glass is durable, heat-resistant, and crystal clear. It can easily be cleaned with a quick rinse under running warm water.
