Nalgene Grip n Gulp Sipper Valve Replacement For Toddler Bottle (3-Pack of 2)

If you hand wash they last forever. For the second child we started to use the dishwasher and they don’t last near as long. It would also be nice if you could buy replacement lids. Because the lids on the inside get to big as well. So a new valve will not stay in place.

These fit the Nalgene cups perfect. Wonderful quality, doesn’t leak or spill at all. I’ve purchased serval of these over the last few years

My first valve lasted two years with constant dishwasher runs, ordered these and they are the exact same item! As we have more kids this multipack is great and will last a long time.

Perfect replacement. Tighter than old worn out ones.

Dont waste your money buying other cups that leak. This cup is leak proof. I only buy nalgene for my toddlers.
