Must have designs 

Studio OOOMS consists of two very smart designers: Guido Ooms and Karin van Lieshout. Both are graduates of the Design Academy in Eindhoven. Not bad, as far as diplomas go. They have been working together for over 14 years, coming up with innovative designs with a high 'must have' factor. Because their personalities perfectly complement each other, they form a very strong team. Guido is responsible for a lot of ideas, while Karin ensures that these ideas are feasible. Together, they are responsible for a wide range of products, including the famous Milkmaid, Puzzle Board and Wooden USB Stick.

They never left school 

They met at the Design Academy in Eindhoven and are now teachers there. They can also often be found at the Utrecht Academy of Arts, where they train young designers. But there's more; they organise many workshops all over the world as well.
