Inner Filling: 100% Pure And Natural Long Strand Silk Floss.
Side Zipper: YKK® Zipper, made from Zinc Alloy (zipper head) and Polyester (zipper teeth and tape).
Temperature Regulation: The breathability and heat insulating properties of silk make sure it is able to keep you warm without making you hot, and its great moisture wicking abilities help keep your bed dry.
Please kindly note that silk pillows are thinner than usual pillows, which is better for your cervical vertebra. Before using the silk pillow, we advise you to flap it to make it fluffy. To keep its filling power, please flap the pillow regularly.
Note: Due to product up-grading, some old versions still use other zippers.
