The all-glass design of Lisbon French press makes it a very unique. It is unlike any other, with it's unibody design. The handle is fused to the body of the press, giving you full visibility and clarity into your gourmet coffee or loose teas. Given this design, it is also a perfect infuser for blooming teas. Although the Lisbon French Press is dishwasher safe, we recomment careful hand-washing and drying to prolong the life of any French press.
