Review on 🚰 WaterWeek Reusable Water Bottles for Kids, 10 oz – Includes 5 Classic Refillable Water Bottles + Fridge Tray – BPA Free, Leak Proof – Kids Sport by Matthew Miles

EDIT: Wanted these but the caps are very difficult to unscrew. Of the 5 bottles, only one has a simple screw cap. I even tried mixing and matching caps with different bottles but they were all stiff and difficult to unscrew straight (difficult for me and impossible for my 6 year old to unscrew straight). The bottles also leak a little - enough to wet the inside of my daughter's lunch box. Too bad it didn't work as I'm having trouble finding a water bottle small enough to fit in my daughter's lunch box along with her small thermos. It's the perfect size for school lunch. They are also easy to clean if you have a soft bristled bottle brush. We haven't used them yet, but I added water to each bottle and shook them to check for leaks. Very little dripped from one bottle when shaken upside down. The rest was fine, so we just use a "leaky" bottle at home where it can't be thrown in a lunch bag or backpack.
