Two boot shaped glasses have been released for the series.
Their retail values, and thus second hand values, are nothing alike.
The first glass, titled Nagagutsu de Kanpai Glass (長靴で乾杯グラス), was released on August 11, 2009. It retailed at 682円 ($9.09).
A second, simply Nagagutsu Glass (長靴グラス), was released June 17, 2010. For this one, the retail value was 3000円 ($40), instead.
