Great for spidey mad kids.
These are absolutely fabulous! Came really quick too. Having the choice of a plastic one or stainless steel is awesome. The stainless steel is great for keeping up with kids. Only draw back I have found is that the straw has actually split on them so they are no longer leak proof, shame as they aren't quick to replace coming from America. If I could easily buy more without the cost and wait I totally would.

Good but...
The top red mouth piece over time goes black on the inside. Been scrubbing it but over time it's nust got worse. Seems the material used is not good.

These cups are great for toddlers especially ones that like to tip cups over. Hardly any spillage!

Really cute cups, perfect for toddlers and preschoolers. The cups are spill-proof (droplets of water will come out if you intentionally turn it over and shake the cup vigorously), but my toddler also complaint that she has a hard time sucking water out. Tried it for myself, and true enough, it takes a lot of effort to draw a small amount of water. Gonna try a hack and nip the valve in the sipper a little and hopefully it'll be easier to drink out from.

Great cup! I love that it has a straw, it’s leakproof and durable. The kids also love the Minions! Buy, you won’t be disappointed.
