ContigoKids Spill-Proof Stainless Steel Tumbler with Straw and THERMALOCK, 12oz., Gummy with Shark

Sturdy, nice size with cute robot printing. But the most important is that it doesn’t leak no matter what my son does!It’s not the cheapest but I’m very happy that finally we got a tumbler for our son that doesn’t make a mess even when he throws it.

Muy recomendables, muy buena calidad, sencillos de limpiar y buena capacidad. Muy recomendables

I love these cups. They are sturdy, durable, and spill proof. I also like the hard straws, because my kids can’t chew holes in them like they have on some other straw cups. They cup apart for easy cleaning in the dishwasher.

The BEST CUPS they never spill

Bom de verdade, meu filho amou. Não vaza, só não consegue usar para suco, tem uma tecnologia para não vazar só passa agua no canudo

I feel like I have looked for years for a stainless steal leak proof kids cup. Another mom recommended this and she was right!! This is leak proof! My kids have thrown it, dropped it, held it up side down shaking it, everything.It has stayed leak proof.The only time this thing will leak is when the inner straw comes off of the top straw. Which doesn’t happen often and is usually my fault for not tightening every now and again.Simply screw it back on and it’s leak proof again.Seriously love this cup so much.The only downfall I can think of is that the straw is plastic. At this point after 100 other zippy purchases I’m just gonna deal with it, since the container is stainless steal and it doesn’t leak.Highly recommend if you have been searching forever for a ACTUAL leak proof cup!
