I am not an expert here, but it has really done well to my health. I've suffered the allergic to cottons for really a long time and silk is always my choice. I used to purchase the bedding from a store in Houston,may I disregard its name? They are friendly, but actually, the bedding is just so-so, not bad & not good. My daughter suggested me last summer of you, your advertisement is inspiring, I am really impressed by that. I believe it will be the best choice I made, and your effort proves that. The quality of the fabric & the mastery of design & construction are amazingly wonderful! Thank you so much, I feel better with my allergy.
