How We Evaluate
What we do
- We report published dimensions in millimetres and show the exact PT-to-inch-to-millimetre conversion.
- We record vendor disagreement as disagreement. Where suppliers publish conflicting micron figures, both are shown.
- We record non-disclosure honestly rather than estimating a missing spec.
What we do not do
- We have not measured any product. Every figure is a published standard or a vendor specification.
- We give no investment or authenticity advice. A sleeve or holder tells you what it is made of and sized for, not what a card is worth.
- We do not predict grades. Supplies do not determine a grading outcome, and submission requirements come from the grading company.
