- I just adore Efrat’s “Vanilla” take on the traditional paper cupcakes and I love her brilliant “Lock Cup” concept. A cup that is designed for people who share workplace facilities such as a kitchen. The cup has a hole which prevents people from using it. Only the owner of the cup can use his shaped key to close the hole, pour the coffee and enjoy the drink. What a startup! BTW “Take it easy” and “Surprise!” were Featured at designboom “Handled with care? exhibition.
