Designer Timo Sarpaneva designed the beautiful Tsaika glasses in 1957. He was inspired to create the Tsaikka glassware after a visit to a zipper factory: the wasted material used in zipper manufacturing results in metal plates with small holes reminiscent of decorative lace. Sarpaneva used these leftover discs in his first Tsaikka glass holder. This elegant glass is perfect for sipping tea or mulled wine, as the holder prevents the drink from feeling hot in the hand. Timo Sarpaneva's work, including the Tsaikka glasses, is celebrated for its innovative approach to materials and form. His designs often bridge the gap between art and practical household objects, making everyday items aesthetically pleasing yet functional.
