Designed by Finnish glass visionary Erkkitapio Siiroinen for Riihimäen Lasi Oy, the Pisara pattern stands as an expressive icon of late 1960s Scandinavian utility glass. Commissioned ahead of Finland's historic January 1, 1969 deregulation of medium-strength beer (keskiolut), the series was conceived as an accessible, beautifully engineered everyday vessel that celebrated the fluidity of molten glass. Its surface is punctuated by cascading vertical columns of embossed dewdrops that taper gently toward the smooth, fire-polished rim, creating a wonderfully tactile hand feel and casting sparkling reflections in ambient light.

Crafted via precision machine-pressing, each glass demonstrates exceptional optical clarity and wall consistency. The underside base reveals an intricate molded relief motif featuring concentric arrangements of clustered bead droplets, trefoils, and a textured foot rim that elevates the base slightly off tabletop surfaces. Designed for everyday resilience yet imbued with sculptural Scandinavian character, these versatile tumblers serve effortlessly as lowball rocks glasses, cocktail vessels, or water tumblers.

This vintage three-piece collection includes two taller tumblers and one coordinating shorter tumbler, all preserved in excellent vintage condition free of chips, cracks, or clouding. The taller glasses measure approximately 3 inches in height and 3.25 inches in diameter, while the shorter tumbler measures 2.25 inches in height and 3 inches in diameter, with the entire set possessing a combined weight of 1.2 pounds.
