Mulberry silk pillowcases are produced by the silk worms, which eat mulberry leaves and are completely natural. The process of mulberry silk pillowcases production is an ancient craft that had been in existence for over 2000 years in China and the old Chinese masters of silk-crafting served no one but the very royal families of China. The art of producing mulberry silk pillowcases have been in constant evolvement and it’s only reasonable to say that after 2000 years, it is really hard for wild silk to top the systematically bred and cultured mulberry silk pillowcases. Generally speaking, mulberry silk pillowcases have better color, smoothness, luster, fiber length, fiber uniformness and elasticity that wild tussar silk, in all its coarseness and dimness, can only dream of having.
You need to make sure that the mulberry silk pillowcases you are getting is made from 100% pure mulberry silk. I have seen numerous cases where the title of the merchandize proudly boasts of “silk pillowcases” or even “mulberry silk pillowcases” and yet somewhere in a little corner in the description lurked a little sentence that read something like “50% silk 50% cotton” or “80% silk 20% polyester”, etc. Don’t be fooled – remember, if a vendor is selling top quality stuff, he probably would like everyone to understand why his products are better; leaving out the decisive “100% mulberry silk pillowcases” hardly seems like the way to do it.
Finally, if you are buying 100% mulberry silk pillowcases offline, I would recommend that you go to whichever store you are interested in and hand-feel the silk yourself, especially with mulberry silk pillowcases which you will be putting your face against every night for a long while. There is nothing like the actual touch of your hand that can give you more assurance on the quality of the product. Of course, that option is not always available with online vendors.
