Flat Bottom Dripper from Hario

This is one of the most expensive drippers now on the market. It's the Hario Flow Tri-Up Dripper. In partnership with Erik Liao, 2023 Taiwan Brewers Cup Champion, this dripper is one of the most innovative product designs from Hario and YES the design works. I would say this is one of those drippers that I've tried for the first time and I could say that this is one special dripper.
