I buy this block for my 2-month-old boy 's first valentine present , but he do not show interest yet -lrb- now he be 3-month-old -rrb- . so I 'll come back to write down comment how he like . I be really happy with how easy to clean these block . I wash by my hand and its shape become badly , but once I put they to drier , the block shape come back ! wow , good ! I do not find any wire taste .
