Superior Fit Sleeves.
I will not use another product on my top loaders or PSA/SGC slabs.
That said, they recently had to delay orders because the newly announced tariffs (Canadian company).
Their website says international orders have resumed, but I have not tested it yet.
Even if they had to raise prices by 50% and it takes an extra 2 weeks to ship, they will be worth it.
