Umeda-sensei, another teacher in the tankokai, has a great many tea things.
I didn’t have a kensui (waste water receptacle). She offered to sell me one, and I was pretty happy when she showed up to Sotanki with a few more things for me. Just because. :)
I haven’t seen these things in a store, not even Asakichi in San Francisco. Let’s take a peek. :)

This was from oiemoto, she said. The kanji looks familiar. Could it be omiyage?
You can hold a tea sensu (fan) and kuromoji inside.
This is also a kuromoji and holder. I think the metal kind may have a different name…

In the koicha (thick tea) ceremony, the guests are sometimes provided with a wet chakin (linen cloth) in order to wipe the rim of their tea bowl after they have drunk from it. But what if you didn’t have many nice chakin to share?
These are disposable chakin. It has a soft texture. 
The last, and most special, was this fukusa (silk cleansing cloth). It features momiji (maple leaves) prominently, so it would be perfect for a Fall chakai (tea event). Wow!

Silver paint! 
I am lucky to have such generous friends. Thank you, Umeda-sensei!
