How I prep a card without cleaning it

Centering is something I can look at. I do not clean, trim, or alter a card on this worksheet.

What this desk is not

This desk is not PSA, BGS, CGC, or SGC. I do not file a grade, a turnaround, or a population.

On 28 September 2026 I still have no supplies aisle to describe. I will not say a button on this host buys sleeves.

What I will observe

I can say whether a border looks even to my eye. That is observation, not a promised grade.

I do not give a cleaning step, a trimming step, or an alteration step.

The line with ultra

I read the cited page, then I stop. The line I can use is: The cited page title is Sports Card Storage & Memorabilia Protection – Ultra PRO International.

I can use ultra and storage from that line. I cannot use them as a grade guarantee.

No grading company endorses this worksheet.
