Inspired by nature, Kastehelmi (Finnish for "dewdrop") from legendary designer Oiva Toikka features rings of raised glass droplets that resemble strings of dewdrops glistening under the morning sun. Each beloved Kastehelmi piece plays with light, bringing out the reflective beauty of the glass. The recycled Kastehelmi tumbler is made of 100% recycled glass produced from waste glass at the Iittala Glass Factory in Finland. Recycled, durable and functional drinkware that suits any table. Perfect for serving water, juice and other cold drinks. Collect a set. Dishwasher safe. Mixed coloured glass results in a beautiful variation of blues, greens and natural earthy shades.
