Product details:

The GROSCHE UltraMesh is a paperless and reusable coffee filter for individual mugs, small coffee pots, or glass beakers. Its mesh is very fine, to extent that it feels like a silky fabric. The UltraMesh has a non-slip grip around the bottom edge to ensure sturdiness when placed on a mug or pot. Paper filters deprive your coffee of the essential oils that are extracted from your coffee grounds. With the UltraMesh's 18-8 stainless steel filter, you can extract all the oils and flavors from your coffee. It also does not trap any of the natural coffee oils, leaving you with the tastiest cup of coffee.
