Duvet cover made of soft combed cotton sateen. Thread count 340. Printed with a hand painted diagonal square pattern. Button closure. Made in Portugal. STANDARD 100 by OEKO-TEX® Sateen has a beautiful sheen and leaves a soft and silky-smooth feel. We weave our sateen from 100% fine-combed cotton. This means that the cotton has been combed so that only the long, strong fibres remain - a prerequisite for creating sateen of the finest quality. Iron your sateen bed linen while the fabric is still slightly damp. This presses the fibres down, which highlights and preserves the fabric's beautiful shine and makes it more durable. Do not tumble dry. Duvet cover and pillowcase are sold separately.
