How does this plastic do with UV exposure over time? How does it fail?
E.g. I made the mistake of using some plastic bins to store plant-related stuff on a mostly-shaded corner of my balcony. One day, when I tried to pick one up, the portion of the lip I grabbed just broke off under pretty light pressure; the whole thing had become weak and brittle. I would hate for a pannier to fall apart and dump whatever I'm carrying at some point in the future when I hit a bump or something.
