This tray for serving soba noodles is made of two pieces: a bamboo frame and mat. The mat is made of thin slices of bamboo about 1/8" wide that are joined together by roping in three locations: one in the middle and two that are equally spaced out on either side. The frame is held together by a simple joinery system and four small metal pins. The outer sides of the bamboo frame and mat have a clear varnish finish.
These trays are typically used to serve zaru-soba (cold buckwheat noodles), generally eaten in the summertime.
