Description

Please read carefully before purchasing:

1.Size Selection

Flat Sheet: The marked "Length × Width" refers to the size of the flat sheet itself. Please select according to your bed size. Normally, the flat sheet should be significantly larger than the bed for a more elegant drape when the edges hang down.

Fitted Sheet: The marked "Length × Width × Height" refers to the size of the fitted sheet. Please select according to your mattress size. Our fitted sheets feature an extra-deep 45 cm (17.7 inches) pocket design, which fits all mattresses!

2.Product Information

The item you are viewing is a single flat sheet or a single fitted sheet. For a full bedding set, please contact customer service. We also offer personalized customization services based on the sizes of your pillows, quilts, and mattresses at home.

3.Material

100% genuine high-end pure silk, namely 100% mulberry silk — a natural animal protein fiber.

4.Product Features

This material contains 18 types of amino acids and is hailed as the "Queen of Fibers". For more details, search for "100% mulberry silk" via AI — it is a top-tier fabric in China's high-end bedding sector.

Kind Reminder: Many mulberry silk bedding products on the market are adulterated and not 100% pure mulberry silk. Mulberry silk fabric itself is relatively expensive, so most low-priced silk bedding products have falsely marked parameters. Please be careful when distinguishing, and remember to verify the authenticity by weighing the product upon receipt.

Most merchants selling low-priced silk offer extremely thin fabrics with poor durability. These products are not recommended for bedding, as their only advantage is the low price. To ensure a quality user experience, we never use overly thin fabrics.

The thickness of this fabric is 129.17 g/㎡ (3.81 oz/yd²). It is an ultra heavyweight 100% mulberry silk fabric. Heavier fabrics command higher prices, yet this product offers exceptional value for money. High-end customers who prefer thick, substantial fabrics should not miss out on this.

We provide precise specifications so you can weigh the product yourself upon receipt to avoid being deceived. Many silk fabrics on the market are blended with other materials to pass off as 100% pure silk — do not focus solely on the price.

All products are custom-cut and made to order. Shipping will start approximately 3 days after payment.

We only offer fabrics that meet the standard thickness requirements. After purchase, you can calculate the fabric weight per unit area based on the product's weight and size — all our products comply with the stated specifications.

We exclusively use Grade 6A double-cocoon mulberry silk filaments with a fiber length of over 1200 meters, which are not spliced from short fibers. Please be wary of low-priced mulberry silk bedding.

Aside from its relatively high price, this fabric has no other drawbacks. Please note that our profit margin is low — the high price stems from the expensive cost of the fabric itself. Due to its high cost, it is also regarded as a luxury accessible only to high-income groups.

5.Washing Instructions

It is recommended to hand wash or use a special detergent. Wash gently in cold water and do not wring. Lay flat to dry and avoid direct sunlight.

Silk is prone to wrinkling. When ironing, use low temperature (it is recommended to place a cloth over the fabric) to prevent fiber damage from high heat.

6.Customization Service

For other sizes, please contact us for customization.
