Review on Bormioli Rocco Quattro Stagioni 33.75 oz Clear Glass Milk Bottle - Pack of 4 by Dawn Atchison

The bottle itself is almost perfect. They are used for almond milk and nothing else. Covers need work. I bought in June and now the inside of the lids are discoloring. The discoloration doesn't bother me other than appearing grayish black and I'm wondering if this is some sort of mold? They are constantly used and stored in the refrigerator. And constantly washed. The covers outside are fine and look like new. So look for replacements, either made of stainless steel or BPA-free plastic. I'm aware of replacement lids for this particular product, but I think it's a waste of time if they don't last as long. In operation were about 4 months. I can say again that I am very satisfied with the bottles themselves. Many Thanks.
