I first saw this mug at the office and I fell in love with it. I had to have one. I bought one and my kids instantly claimed it to be their own. Applying the legos proves to be soothing and calming. One can spend countless amount of time with the mug. When one is stressed, the mug can be a stress reducer. The mug can be used for people of all ages (with the exception of age restrictions). When the legos prove to be a problem, younger ones can enjoy a refreshing sip from the mug. Purchase one for yourself. It will be one of best decisions you make in a long time.
