I purchased the taupe mulberry silk pillowcases , and they are totally awesome. I have never slept so well, they feel superior in every way, the softness, everything-can't put it into words how amazing they are. I didn't expect to get the pillowcases with the zips, as normal pillowcases don't have them-this is so much better than other pillowcases. Due to my severe dust mite allergy, dust mites that are in every pillow, certainly don't affect me anymore. I'm going to be buying more products from Calidad Home. If you really want the very best in silk, made to the highest standard, with a zip (which is perfection)-buy from Calidad Home, and nowhere else, as you will end up regretting it. Best silk products I have ever bought-thank you Calidad Home!
