Product design is usually all about combining functionality with aesthetics. On rarer occasions, it offers the designer a chance for some tease and mischief. They say that opportunity comes knocking at our doors in all forms, and clearly, even in the form of a humble milk bottle. With some etching cream and a stencil, this would now be a fairly simple DIY project. But I continue to be awed by the kind of ideas and thinking that go into these products the first time they’re rolled out. I sometimes envy the deviously creative minds, and I wish I could rent it from their owners just once in a way!
