Iitala Aino Aalto Tumblers
First designed in 1932, the distinctive rings were inspired by the rings made when a stone hits water, but behind this lies the practicality of glasses that are stackable and versatile. The tumblers are available in two sizes (22cl or 33cl) and in a selection of colours – apple green, grey, light blue, water green or clear. They cost £12 per pair for the small size and £18 per pair for the larger size. A tad expensive for glasses, but cheap for a design classic!
