I've just received a new teapot from Den's, the $19 Kokoro
(one of three $19 pots they sell currently with similar, but not identical specifications).
I don't know of anyone else who has one of these economy pots, but it seemed safe enough to take this one for the team.
It's a handsome little pot, as seen in this "fresh from the box" footage
It pours just fine, as seen in this rare "first cup of tea from a new pot" footage
If you're looking for a sencha-friendly teapot that passes cost-benefit analysis, you could certainly do worse.
My wussy phone cam once again fails to do justice to a gorgeous cup of sencha, but whatcha gonna do?
