About Safely Sleeved
Card protection explained from measurements and materials rather than opinion, with every factual claim traced back to the manufacturer or institution that published it.
Safely Sleevedcovers the things that protect collectible trading cards: sleeves, binders, toploaders, rigid holders, display cases and storage. We give sizes in millimetres, name the plastic a product is made of, and say what each item won’t protect against.
Why this site exists
Almost everything written about card protection is a ranked list of products. Those lists rarely tell you the two things that actually decide whether a card survives: what size it needs, and what the plastic touching it is made of.
Both are knowable. Manufacturers publish sleeve dimensions and holder thicknesses. Conservation bodies publish guidance on which plastics are safe for long-term contact with printed material. Grading companies publish what they will and will not accept. We are trying to put all of that in one place, in a form you can check for yourself.
Some of what we found is unhelpful to product marketing. The standard rigid toploader is PVC, by its manufacturer’s own description. Some binder pages are vinyl, which is also PVC. “Archival safe” is not a measurable standard, and the institutions that would define it say so. All of that is cited on the relevant pages.
How the content is written
One rule sits behind everything here: we never publish a measurement, material or compatibility claim from memory. Every figure gets checked against a manufacturer listing, a grading company’s own documentation, a preservation institution, or a rules document from the game’s publisher. We then link that source on the page that uses it.
If we can’t source a claim, we don’t publish it. If we could only reach a source indirectly, we say so instead of hiding it. The methodology page explains which sources we trust over which, and what we do when they disagree.
We treat corrections as part of the job rather than something to be quiet about. When a claim turns out to be wrong we fix it and leave a note next to the copy, so the same mistake can’t creep back in later. There is a worked example of one on the methodology page.
How this site makes money
Through Amazon affiliate links. Some pages carry a “What we’d buy” block, set apart under its own heading after the page has answered its question; if you buy through one of those links, Amazon pays this site a commission and you pay the same price you would have paid anyway. There are no adverts, no sponsored placements, and nothing for sale here directly.
The rules we hold ourselves to. Affiliate links appear only beneath a heading that says what they are, and only on pages finished enough to stand on their own. Every other outbound link on the site is a citation, earns nothing, and is there because some claim depends on it — if you can’t tell a citation from an advert, the citation is worthless.
No manufacturer has paid for a place in a recommendation, and a product is never listed unless it publishes what it is made of. That rules out a good deal of what sells well, which is rather the point: the commission is not worth the one thing this site has.
What is not here
No price tracking, no card valuations, and no investment advice of any kind. We cover protection and storage. What a card is worth is a different question with different sources behind it.
No product rankings that aren’t grounded in a specification. Where two products differ in a way you can measure, we give the measurement. Where it comes down to preference, like shuffle feel, artwork or brand, we say that it’s preference.
Corrections
If something here is wrong, we want to fix it. Claims on this site are deliberately specific enough that you can check them against the sources listed underneath. A page vague enough that nobody could ever prove it wrong isn’t telling you much.
