This seems like good thinking, and a very striking device. I like the ability to use filters I already have, and it's a little reminiscent of folding up paper filters with the CHEMEX system. I just started watching this video and thought "Why don't I ALREADY HAVE this?". Really, I just need to go shopping in Japan. Well, let's see if there's any supplier. I hope there's a model that uses #1 size filters for practical reasons but that might not be practical. Thanks for your dedication and care!
