I bought this new and have never used it. 

The Nest Pour Over Kit incorporates double  walled stainless-steel construction with a BPA Free lid and storage connector into a rugged, portable pour-over coffee brewing system. Dual threads enable the 5-piece kit to assemble into one compact unit perfect for travel, overlanding and other outdoor endeavors. When disassembled, the Kit delivers two 10oz mugs, one splash proof lid, a pour-over dripper, and a nesting storage connector that allows the system to be compatible with the Java G25 Grinder (which is included). This holistic coffee brewing system delivers a premium brewing experience. Anywhere. Everywhere.
