This weekend I decided to re-make WAV files of all my Cobra Soft originals in order to test them with Cobr2tap.exe

Among 11 of them, two of the VHS-like white boxes litterally fell into pieces when I tried to open them: the plastic is dry and simply pulling a little to try and open breaks it and makes a LOT of tiny plastic pieces.
They are stored in a cardbox, in a dry room inside a house, couldn't do better.

Does anyone know if there's a way to prevent the plastic from drying, or do we have to accept this the fate of some plastic boxes after 38 years?

I've only three of these (Cobra Pinball, Formule 1, Meurtre a Grande Vitesse), and as far as I can see, both the external white case and the small white plastic form that keep the tape inside are in ok condition, did not break when I opened them to test.
