Haiken (拝見) is the close-up, ceremonial viewing of the utensils used to make tea.
Haiken dialogue for usucha:
O-kyaku-sama:
"Douzo, o-natsume o-chashaku no haiken onegai itashimasu?"
"May I please have a closer look at the tea container and tea scoop?"
The host purifies the implements and leaves them for the guest to examine. When the host returns:
O-kyaku-sama:
"O-natsume no katachi wa?"
"What type of tea container is this?"
Teishu:
"Rikyuu-gata chuu natsume de gozaimasu."
"It is a Rikyu style tea container of the middle size."
O-kyaku-sama:
"O-nuri wa?"
"What is the style of the lacquer work?"
Teishu:
"Sotetsu de gozaimasu."
"The lacquer work is in the style of the Sotetsu family."
O-kyaku-sama:
"O-chashaku no saku wa?"
"Who made the tea scoop?"
Teishu:
"Zabousai o-iemoto de gozaimasu."
"It was made by Zabosai, the head of the Urasenke school."
O-kyaku-sama:
"Go-mei wa?"
"What is the name of the tea scoop?"
Teishu:
"Wakei/Buji chashaku de gozaimasu."
"The name of the tea scoop is harmony/peace"
O-kyaku-sama:

The type of natsume, its lacquer, and the maker and name of the tea scoop will obviously vary depending on circumstances. You can choose a gomei to reflect the season or occasion.
