Is it really leakproof?

It resists spills because the valve opens only under suction, but it is not fully leakproof. Hard drops or a worn valve can let liquid out.

How do you clean the valve?

The cup and lid are dishwasher safe. The silicone valve should be pulled out and rinsed by hand so milk or juice does not build up in it.

Munchkin positions it for babies transitioning from bottles, roughly 6 months and up. It works best once a child can sit up and hold a cup.

This 2-pack is the basic trainer cup with the 360-degree rim. It does not include handles or a travel cover.

At $14.78 for the 2-pack at Munchkin as of November 8, 2026, that is about $7.39 per cup, in line with typical pricing for this set.

Yes. The cup, lid and valve are machine washable, though hand rinsing the valve first helps.
