I bought my son this thermos for school. Cool color, made of metal, so no unhealthy plastic ... Are you kidding me? Are you serious when you say that! The long -and added density screw stank after a while so ill after gammeligem plastic, so that my son the full Wrong brought back simply with the comment "it stinks again". In addition, the blue paint Scrubs easily from the sides slide into the knapsack when, and then she looks garnicht more cool! I had stupidly ordered two wrong ... now the hike both in the garbage! Waste of money!
