The plastic is too thin and very brittle. I have all the models of this series in my collection (some more than once) but there is not a single one which does not have a crack somewhere in the casing. Most often around the battery door. And most of them have badly corroded battery contacts and also corroded or completely dissolved PCB traces. This is because there is nothing which prevents a leaking battery from contaminating the entire calculator. And again, most of them have developed battery leaks over time because the "constant memory" keeps drawing current from the battery until it will be deep-discharged. Something which does not happen with a 67 for example.
