I bought these for my son when we started the process of him using cups and I had too end up throwing all these cups out. The cup comes in like 3 separate pieces. The bottom base for your liquids, the 2 top pieces that screw on top of each other too hold the liquids in. Well everytime I gave this too my son it would constantly drip from the straw area and the sides. I could NEVER get the cup too seal properly. Even my husband had issues trying too close the cup properly and it would leak all over the house. I just ended up throwing them all away too buy a simple training cup with a base and 1 lid. Its also a pain too have too clean all these pieces as well and then trying too figure out the puzzle of screwing a cup together with a screaming frustrating child who wants there water asap LOL....

Costs about 6.99 for 2 cups at Walmart
