Oak is a wine glass from BOBO, designed in collaboration with Sebastian Gibrand and Niklas Ödman. The glass is mouth-blown in lead-free crystal and holds approximately 65 centiliters. It has a height of around 20.5 centimeters and features an ultra-fine rim. The thin bottom and stem contribute to a sense of lightness. As each glass is handmade, variations in thickness occur, typically ranging between 0.4 and 0.8 millimeters.
