This is confusing to me. The card doesn’t touch the surface of the slab - only the edges are in contact with the plastic. So is this referring to microscopic edge wear?
This fact is verifiable by their patents filed decades ago.

“No Mylar, no sleeve, no movement”… Does that mean they’re completely getting rid of the inner sleeve for cards that are too small? The vast majority of slabs don’t have a sleeve anyway so I’m curious what they’re talking about here. I also don’t see how a change in plastic would remove the need for an inner sleeve when the card is too small.
Ah, yeah I middle man for a middle man and I get PSA returns back through USPS, my mistake on that one. I can’t imagine going from 5 pounds to 6 pounds through Fedex or UPS is a significant price increase
36:10 minute mark Nat Turner talks about this “we very quietly have rolled out a new slab” - 9 months ago.

The card can’t just float in mid air in the slab, so either the front or back surface is in contact with the plastic. Atleast on the examples where the card can move up and down inside the slab and isn’t secured well
Only the very edges of the card touch the plastic (best visualized in the patent itself) so the “face” of the card is barely touched at all. It’s a pretty genius design.
Please read the conversation here. The card does not touch the front or back surfaces. The contact of 2-3 edges (soon to be 4) hold the card perfectly between the surfaces.
Exciting times when we can finally take our PSA cards to go swimming!
But in all seriousness, these are all much needed improvements to their slabs. The subtle differences will make an impact for the consumers.
I vaguely recall a thread on E4 years ago discussing why PSA slabs were kept intentionally porous - was it to prevent the risk of encapsulation in a higher humidity environment? Or was that only a theory poised by a community member?

wonder if that slab i received a few weeks ago that was also about 20% heavier and made of a different material turned out to be real all along 
nah couldnt be

I wonder if the upgrade is comparable to CGCs slab clarity

“Medical-grade,” presumably ISO 10993-certified plastic is an interesting thing to advertise, but I love the sound of heftier slabs.
Unpopular opinion but the biggest upgrade of all would be to change the design

Straight up, all my homies are obsessed with ISO 10993 certified plastic. They never shut up about it. They’re going to go nuts when they hear this!

Shrapnel from cracking is now 110% cytotoxically safe, hallelujah.

I hope the heavier case is not more difficult to crack open. Although it will take a long time before these have critical mass as a percentage of total slabs.

Finally, I can perform surgeries without worrying that my slabs aren’t medical grade!
Have to wonder if the little moulded arrows that appeared on the top back left during the 7xxx cert slabs & have now disappeared around the 87xx certs, mark the transition to these newer slabs (if they’re already out there)?
Here’s an 83xx cert on the left & 91xx cert on the right. Notice the little upward arrow & set of bars on the edge of the older slab version that’s now gone:

Heavier?? So more shipping for international.
And when shipping is more expensive there will also be more taxes to pay.
Not needed from my point of view.

International Shipping will be more expensive.
Each POUND counts and adds up very fast.
