Review on 🥛 Bormioli Rocco 4oz Stackable Beverage Glass by William Turner

I rarely rate anything low. But I found these glasses to be defective and dangerous. I've had these glasses for about a month and I'm very happy with the style and how nicely they fold. However, one glass spontaneously exploded while sitting in a colander on my counter that I had washed out earlier in the day. The only thing I can think of to explain this is that it has been washed many times in my dishwasher and it is possible that its internal glass joints have changed because it is tempered glass. Maybe it's made from recycled glass? It was strange. But at least no one drank from it back then! The shards exploded into many cube-like shapes instead of shards of glass.
