The Milo Cup

This is Eye Cup #11, The Milo Cup.  My two-year-old nephew saw one of my eye cups at my parents' house and was fascinated by the eye on the inside that appears when you've finished drinking.  So this is an attempt at a kid-sized eye cup.  I say attempt because the rim is too thick for me to drink out of comfortably, so I'm guessing it would be more difficult for Milo.  But hopefully it can be put to some use, even if it doesn't last long (young children and fragile ceramic = ...).
