Munchkin 2 Pack Miracle 360 No Spill Sippy Cup, 10 Ounce, Orange/Blue

They are a nice add to the regular 369 cup. However they do not keep milk as cold as I hoped. It’s a step up from the regular cup. Just wish they kept drink colder for longer. Not comparable to a yeti

They do leak some. My grandson has special needs. He likes to shake his drinks causes some leaks. But the durable out weigh the small leaks.
