For Tetris-addicts out there, you might want to know that there’s Tetris Soap being sold on etsy. These are just simply AWESOME! And yes, if you have OCD (like me), these would do. (OCD = Obsessive Compulsive Disorder or really clean.)
For people with OCD like me, you might get some fulfillment from trying to make these Tetris pieces fit perfectly together before washing your hands of them….mwahahah.
