Tapio liqueur glass 9 cl 2-pack from Iittala. Two small hand-blown glasses made using the pipe glass blowing technique, which causes a characteristic glass bubble to form in the stem. The elegant glasses have a beautiful silhouette and were designed by the Finnish designer Tapio Wirkkala in 1954. The designer created the special pipe glass blowing technique where a glass bubble is created with the help of a wet stick. The liqueur glasses are part of the Tapio glass collection, which is the most long-standing collection on the Finnish glassware market.
