FAQs
What makes Grade 6A silk different?
Grade 6A is the highest quality long-strand silk available. It ensures the most uniform texture, highest durability, and a signature pearlescent luster that inferior grades lack.
How do I wash my silk pillowcase?
We recommend machine washing on a delicate cycle with cold water using a pH-neutral silk detergent. For best results, use a mesh laundry bag and air dry away from direct sunlight.
Will silk really help my skin and hair?
A silk pillowcase offers a smooth surface against your skin and hair. Choose the size and closure you prefer, and wash it regularly according to the care instructions.
Is THXSILK safe for sensitive skin?
Absolutely. Our silk is OEKO-TEX® Standard 100 certified, meaning it has been tested for over 1,000 harmful chemicals. It is naturally hypoallergenic and non-irritating.
Do you offer a warranty or trial?
