All about this product

Bring a piece of Holland into your everyday life with the Windmill mug from the IZY Delft Blue Collection. The Dutch landscape with stately windmills, immortalised in Delft blue, adorns this insulated mug from every angle. Inspired by the iconic Dutch polder landscape with its windmills — an image that has made the Netherlands famous the world over.

Thanks to its double-walled vacuum insulation, your mug keeps drinks cold for up to 24 hours or hot for up to 12 hours. Fully leak-proof, CO₂-neutral produced, and with every purchase we donate 500 litres of clean drinking water via Made Blue. A stylish way to make a real impact.

A piece of Holland, always with you.
