Unsealed Donic BS and Tibhar MX-P

The sheets of Donic Bluestorm and Tibhar MX-P I received from Dandoy came naked in their cardboard packaging inside thin plastic sleeves with round perforations. In other words, completely unsealed. Is this normal? Don't these rubbers start degrading the second they're exposed to air. If so I don't know how long they've been sitting essentially opened at Dandoy before they were shipped to me.

Hi, I am curious about the packing. can you please send pictures ?

Thanks for the responses, guys. The packaging is long gone. I was expecting them to be vacuum sealed. They weren't; perhaps they don't need to be.

I have just received and glued a MX-P. What puzzles me is how could we know when the rubber was produced?  Is the factory tunning still there? The only way I guesss is to wait and see if the rubber will drop the performance after 3 months or so     

I got in from Amazon.de. Actually I don't care if the rubber is tuned or not. Even better if the booster is gone cause I like it the way it is. To me more important is to maintain the same characteristics after let's say 5-6 months at least. This rubber stays on my competition blade and I will not use it more than once a week
