Here is one more little travel chabako I put together recently. I found the metal box at a resale shop, and a vintage collapsible cup with a lid for the kensui (bowl for discarded rinse water). I made a chakin tsutsu and furidashi with marbled clay and small white stoneware chawan with similar colors.
The chasen is extra small so I will use the plastic container as the tsutsu until I can find time to make one of aluminum. Also, in bottom center of photo is half of a screen ball-shaped tea-infuser that I use to sift the matcha. Instead of a lacquer natsume I use a tin container that matcha came in when I first began lessons in the 80s. (not in picture.)
