Here, the 茶箱 is brought in on a flower-shaped tray called 花形盆. It was designed by Ennōsai (XIII), so I guess he made some adjustments to Gengensai's 点前. For this one, the 道具 are still wrapped in 仕覆, and the host turns slightly towards the guests.
➡️ Even though you turn slightly towards the guest, the 建水 stays in 風炉 mode (unlike 略盆)!
💪 When leaving, it's a bit awkward because you put the tray in the middle, and then directly from there pick it up to leave (touch and go). I'm not a big fan of that (even though KM26 thinks it's still preferable), so I'd just leave directly.
The 道具 used here are festive and relate to the happiness of spring; so a shiny 鉄瓶, a lacquered 茶箱, a happy 茶碗.
