Gusta glass

Gusta FIKA glass 400 ml. This coffee or tea mug has a single-walled glass made from borosilicate glass. This glass falls under the 'hard glass' category. It is stable, strong and easy to drink from. Hard glass does not mean that it cannot be broken (it is possible), but it needs more heat to melt than standard glass. Resistant to high temperatures! Set of 2 pieces.
