Review on 🥤 Stay Hydrated with Ello Dash Tritan Plastic Kids Water Bottle: Silicone Sleeve for Safe and Fun Drinking! by Alexis Hughes

I was so excited to try them and ended up having to get a refund after throwing both of them in the trash. The locking feature was great and they're really airtight, but they started growing black things, mold I think. it won't come off. They have never been used with anything other than water and never left there for any length of time. The outer cover was also scratched easily, and scratches soiled in the ridges could not be removed.
