'100% Silk' Can Mean Two Very Different Things

This label can describe the entire outer fabric (the most common and honest use), or sometimes only one side of the fabric when the other side is polyester — a less common but real practice. Checking that the composition applies to both sides of the pillowcase avoids this ambiguity.

The Three Details That Prove Authenticity

A serious product page consistently mentions three elements: the exact composition percentage, the momme grade, and ideally a traceability certification (like OEKO-TEX for the absence of harmful substances). Missing all three isn't necessarily fraud, but it does mean asking the seller directly before ordering.

"A real '100%' is proven with numbers and certifications, not just the word itself repeated several times on the product page. "

Three Boxes Ticked, Zero Doubt

When these three elements are all present on a product page, there's no longer any reason for doubt. It's precisely the absence of one of them that should prompt questions before reaching for your card.
