Good for the marinade that's great. Already in two hours the meat is well marinated but what is even better is that you can put the meat to marinate for three or four days without worries because no air = no Tenderising. You can put whatever you want in fact I do not know why they say here in France marinade special but good. Otherwise cracks level I have nothing at all. I advise to maintains boxes simply hand wash with dish soap and a soft sponge. especially not Congelo or dishwasher which undergo thermal shocks that said plastic "classic" can not stand. nickel not to throw scraps that keep for days and days. Furthermore you can for example put in your salad and put in a cold place in your refrigerator. it will keep longer and will not freeze. XD
