Why a Cheap 'Silk' Pillowcase Should Raise a Flag

Real mulberry silk is expensive to produce: raising silkworms, hand-reeling cocoons, delicate spinning. A pillowcase priced at 15-20€ at a general retailer structurally cannot contain real silk at that price — it's mathematically a polyester-satin blend, even when the word 'silk' appears on the packaging for marketing purposes.

What Big Retail Chains Actually Optimize For

General retail chains and large marketplaces are excellent for accessibility and price — not for material specialization. Their business model relies on volume and tight margins, incompatible with sourcing real mulberry silk in small, quality-controlled batches.

"The word 'silk' on packaging isn't legally protected the way '24-karat gold' is — any satin fabric can be marketed as 'silk-effect' without ever technically lying. "

The Question Isn't 'Where' but 'How to Verify'

Regardless of the retailer: the only real guarantee remains a detailed composition sheet and a clearly stated momme grade. A specialist brand that documents its sourcing precisely remains the safest choice for authentic silk.
