Zak Designs Marvel Spider-Man 18/8 Single Wall Stainless Steel Kids Water Bottle, Flip Straw Locking Spout Cover, Durable Cup for Sports or Travel (15.5oz, Non-BPA, Spidey and His Amazing Friends)

Have washed the two of these that I bought a few times and there is still a really metallic taste that doesn’t seem to be fading, let alone going. Expensive bottles that we won’t be using

It's a very good cup and my toddler loved it! Unfortunately, the cup didn't stand up to normal use. We've only had it a couple weeks and today he dropped the cup at nursery and the red lid broke off. I'd like to order a replacement top for it but don't know how to get it separately.
