The fantasy of pearling raindrops has been captured in this drinking glass - a bit impertinent and yet very elegant. Using a complicated glass-blowing technique two kinds of glass are processed until clear bubbles appear to float freely inside the coloured glass tumbler. Handcrafted drinking glasses can be washed in the dishwasher. However, to enjoy long years of clarity in your glasses, we recommend washing them by hand or in a separate glass-washing cycle.
