The host of a tea ceremony party does not provide kaishi because it is used mainly by guests, and basically, the guests should put kaishi and other required items into a fukusa basami (pouch for a silk wrapping cloth and other small items used for the tea ceremony), which is also called kaishi ire (literally, "kaishi pouch"), and bring it to the tea ceremony party.
主に客側が使うため、亭主側が用意するものではなく、基本的には客がそのほかの必要な道具などとまとめて袱紗挟み（懐紙入れ）に入れて持参する。
