      Cool, Quiet Luxury for Your Face (and Your Hair Thanks You Too)
      Color: 01 - Ivory, Size: Queen, Color: 01 - Ivory, Size: Queen
      This is one of those products where you immediately understand the price the second you touch it. First off—this definitely IS real silk, not satin, which is important to verify (esp at this price point). There are so many listings on Amazon of bonnets and pillowcases, sheets etc claiming “silk” and when you get it, it’s satin. This pillowcase is 100% mulberry silk, and you can feel it immediately. What surprised me though is that I actually have other 100% mulberry silk items (my daughter’s play silks from Sarah’s Silks), and somehow this pillowcase feels way smoother and more luxurious than those. Same material on paper, totally different experience in real life. From what I can tell, it’s thicker and more tightly woven, which gives it that extra silky, almost glassy feel. It’s buttery smooth, lightweight, and has that cool-to-the-touch finish that’s honestly a dream in the Phoenix, AZ heat, where it’s already 105 in March. Getting into bed feels like flipping your pillow to the cold side… every time. 🧊 It fits a standard queen pillow perfectly (mine’s a thicker foam pillow and slid right in with zero struggle), and the hidden zipper is secure without being annoying. No bunching, no slipping off mid-sleep—just stays put. And it’s not just nice—it’s doing something. My hair definitely wakes up less chaotic, and it feels gentler on my skin overall. One of those quiet upgrades you don’t think about much… until you do. The ivory color is soft and clean-looking, very effortless luxury, and I like that there are other color options if you want to switch up the vibe. Yes, $60 for a pillowcase sounds a little wild—but this actually feels like a $60 pillowcase. Thick, high-quality, and genuinely luxurious, not pretending to be. If you’ve been on the fence, this is one of those small changes that makes your whole sleep setup feel elevated.

      Beckham Hotel Collection 22 Momme Silk Pillowcase
      Color: 04 - Cherry Pink, Size: Queen, Color: 04 - Cherry Pink, Size: Queen
      This is a 100% Mulberry silk pillowcase (22 momme, 6A grade) in the Cherry Pink color, Queen size. Unboxing and Prep Out of the box, the silk had noticeable deep creases from being folded. I hand washed it and air dried it, but the wrinkles remained. I used a steam iron at approximately 300F with a flour sack towel as a pressing cloth to protect the fabric. It took two passes to get most of the wrinkles out, but the silk held its sheen well throughout the process. Zipper and Construction The zipper tracks are hidden behind a fabric flap so you don't feel the teeth. However, the zipper pull is not fully integrated or tucked away; it hangs free at the end of the track. The pull is small enough that it hasn't been an issue or gotten in the way during use, but it's worth noting it isn't completely "invisible." Fit and Quality The Cherry Pink is a very light, subtle shade. The 22 momme weight feels substantial and opaque. I paired this with a high-loft Sobel Westex Bellazure Duo (feather and down) pillow. The Queen size fits perfectly and the silk stays smooth and cool. Final Thoughts The build quality is solid and the Oeko-TEX certification is a nice touch. To get the best results, you really need to pair this with a high-quality, fluffy pillow to fill out the case properly. On a flat or low-density pillow, it wouldn't look or perform nearly as well. It requires some maintenance with the hand washing and ironing, but the feel is much better than thinner 19 momme options.

      Luxuriously Soft & Cooling, But Needs a Wider Opening
      Color: 03 - Champagne, Size: Queen, Color: 03 - Champagne, Size: Queen
      I really enjoy sleeping on the Beckham Hotel Collection Silk Pillowcase—it has such a silky, smooth feel that makes a noticeable difference in comfort. It feels wonderful against the skin and hair, and I especially love how it helps keep my head cool throughout the night, which leads to a restful sleep. The color choices are also wonderful and look very rich, adding a nice elegant touch to the bed. It’s also held up nicely in the wash, which is always a plus for something this delicate. That said, I’m giving it 4 stars because of the zipper opening design. You lose about 4 inches of usable space at the opening, which makes it harder than expected to insert a pillow. Unlike other zippered pillowcases I own, the ends don’t open wide enough, so I had to squeeze my pillow in—and I actually noticed the stitching starting to pull a bit because of it. A wider opening would make a big difference. Overall, it’s great to sleep on and feels luxurious, but for the price, I do think the design could be improved.
