Review on 🚰 Justfwater Sports Glass Water Drinking Bottle with Silicone Sleeve and Leak-Proof Lid, 14 oz / 22 oz / 32 oz by John Collins

So I bought this product to use for my baby's milk. I liked that it's BPA-free and glass-free, so it should be easier to clean and shouldn't collect with those pesky bacteria you often hear stick to plastic. I really liked this bottle, it comfortably holds 16 ounces of baby milk until a week later when I noticed dark mucus had built up on the inner ring of the cap. I'm very clean and careful, especially when I'm handling my daughter's clothes, so it's not because I haven't washed them. I've cleaned and soaked it and all I can suspect is some kind of sealant leaking out. This is used to store my baby milk and I don't feel comfortable using it anymore. I want the seller to respond and replace.
