These handsome legs will raise a goban by almost 13cm, turning a table board into a floor board (provided that your board has the requisite chiseled slots). They are a lovely light yellow color, and would fit well with a Matsu or Kaya board.
They are 12.8cm tall, 8cm wide. Each peg on top is 2.3cm tall and 2.5cm wide.
