Set of 4 Bicos Highballs Glasses - Blue

The first known reference to these glasses known as "biquinhos" (spikes) is from a catalogue of the Nova Fábrica de Vidros Marinha Grande (New Marinha Grande Glass Factory) - Ivima, 1901. This type of glass, set in the universe of diamond-tip manufacturing, was produced in the nineteenth century, through manual cutting techniques.
Later these began to be produced by the press method, which lasts until today.
