vacuum storage bags to store TT rackets

I didn't but this is a very good idea for the people seldom playing. For those who train, their play may destroy the rubbers before any oxidation has a chance to kick in however the price of a vacuum bag is nothing compared to what we spend on rubbers so why not since the benefit is not null and the routine is easy to install?

Also some rubbers shrunk a lot. So the bags don't help that part. I don't know what to do with small rubbers that can't be play.

Adhesive protection sheets work very well and are simpler to use.

To keep it short, the pressure difference will cause the gas within the cells to escape to the void between the topsheet and sponge at a faster rate than it would if it were stored at atmospheric pressure.

I can't think of a practical method to keep your rubber from oxidizing.  Most people don't have a convenient source of nitrogen or argon at home.  I think zeio is right that a vacuum would deflate the sponge, but maybe you only need a slight vacuum?  Maybe there is a middle ground somewhere?

I like that guy on fb and yt, it's really cool he can make a living doing this.

Would this ruin the rubber though, isn't this a reversible process?
