"WHISKEY WEDGE" is a whiskey glass that allows you to make triangular ice in the glass. Developed by the American miscellaneous goods brand "CORKCICLE".
To use, just put the attached silicon cover on the glass, pour water, and freeze it. By pouring whiskey along the slope of the ice, you can add a scent and enjoy the beautiful contrast of the two colors. It melts more slowly than the ice in the cube, so it's hard to dilute the sake.
The capacity of the glass is 240 ml, and the price is 3,000 yen (excluding tax). In Japan, it is sold by the general merchandise maker Spice, and can be purchased at the company's online shop "ABBOT KiNNEY JAPAN".
