I saw this cup at acquaintances. They had bought a few pieces of your two kids. So far, all are safe and that although the parts are quasi in 24/7 use (home, playground, elementary school, etc ...). The material is really very robust and holds virtually every child everyday stood.
Therefore could not find anything negative and have therefore appointed as the first test a for my little cousin. He also should have some fun with it, a set of mugs will probably follow.
