What does OEKO-TEX 100 certification mean?
OEKO-TEX Standard 100 is an independent certification that tests textiles against a list of known harmful substances. A certified fabric has passed these tests. It does not make any claims about skin benefit or therapeutic effect — it is a materials safety certification. Full details at oeko-tex.com.
What is grade 6A mulberry silk?
Grade 6A is a grading term used within the mulberry silk trade to indicate the highest quality classification — long, unbroken fibres with consistent texture. It is a materials grading standard, not a regulatory or independent certification. The grade affects the feel and durability of the finished fabric.
How do I wash a silk eye mask?
Silk requires gentle care. Hand wash in cool water with a mild detergent, or machine wash on a delicate cycle inside a mesh laundry bag. Do not wring or tumble dry — lay flat to dry. Refer to the Sleep In Beauty care instructions for specific guidance on this product.
What colours are available?
The SIB® silk eye mask is available in multiple colours including Black, Silver, Green, Pink, and others. Select your preferred colour at the point of purchase.
What size is the mask?
The mask measures 20.5 × 8.5cm. This is a standard sleep mask size designed to fit most adults. The elastic strap is adjustable for comfort.
