Review on 💎 Included Décor Gemstones for Coloring by Brian Cox

I would like to give 5 stars because my daughter loved it. It was one of her birthday presents. She brought him to school with water several times. A few days ago she poured juice into it and left it in her room overnight. The next morning she took it to the sink, rinsed it out and left it there to wash. When I started washing dishes, I realized where the stains are on the sides and bottom. I shone a light on it and it's mold. I've never noticed this with water so I've tried cleaning it but it's not that easy as the hole is very small. I also noticed rust around the hole you drink from. I'm uncomfortable with my daughter holding this to drink from. I'll stick with plastic from now on. Other than that, it's really cute.
