I am a big fan of the Mr Sci Science Factory, if you take a look you will love all their products, original, curious and always surprising. That's why when I saw this cute 3D Vase I fall in love at first sight, even without noticing who the creators were!
The Rubin Vase 3D it's the famous ambiguous two-shaped vase that depending on who looked at it can see a form or another. Mr Sci Science Factory has created some original sticky notes based on this form, so when you open the vase (thanks to the magnets), you will have a pretty vase... and you will decide what you see, a vase or a face! ;)
