    Silk Pillowcase Product Review: Mulberry Park Silks vs. THXSILK

    If you’re in the market for a silk pillowcase, congratulations on a smart decision! A silk pillowcase is a great investment in beauty and wellness. It can protect your hair from tangles breakage and bedhead; minimize sleep wrinkles; and help keep your hair and skin moisturized while you sleep. Even better: it’s the absolute pinnacle of luxury. Nothing compares to the feeling of sleeping on pure silk.

    At Mulberry Park Silks, we’ve made a mission of selling the finest quality silk on Earth at fair and affordable prices. We also value transparency, and are happy to compare ourselves to any of the many brands on the market. We think it’s important to teach our clients how to evaluate the quality of a silk pillowcase and to assess all the other variables including style, price, service, and hidden costs.

    Mulberry Park silk pillowcase vs. THXSILK silk pillowcase 

    In this blog, we’ll be comparing the Mulberry Park Silks 22 momme weight* pillowcase with the 22 momme pillowcase from THX silk. We’ll take a deep dive into the quality, feel, features and pricing of each product. We want you to shop smart for silk and get the best value for your money.

    *Momme count is a unit of weight measurement for silk. A higher momme weight silk pillowcase or silk sheet set will have proportionately more silk in it and the individual silk fibers will be thicker. In this way, momme is similar to thread count for a cotton pillowcase or sheets.

    THXSILK Silk Pillowcase

    THXSILK Quality

    THXSILK pillowcases are made from 100 mulberry silk of high quality (6A). The pillowcase is OEKO-TEX® Standard 100 certified free of harmful chemicals and available in ten colors: Grey, Pearl White, Charcoal, Champagne, Charming Pink, Metallic Gold, Black, Purple, Emerald Green, and Red. THXSILK pillowcases are machine washable with care instructions found on the label inside. There is no blog on the website.

    THXSILK Design

    For purposes of this review, we are evaluating the 22 momme pillowcase which is ONLY available in hidden zipper closure (the envelope closure style is a pillow sham with a decorative flange, not a pillowcase, which is meant to be slept on). The seams are plain. The zipper closure seems to be of adequate quality and there were no obvious loose threads to get caught in the zipper. Along with the potential for the zipper closure to break, however, this type of closure is not always preferable; depending on the pillow insert and sleep position, some people may find that a zipper pokes them and makes them uncomfortable during the night.

    THXSILK Company / Companion Products

    THXSILK appears to be a wide-ranging silk bedding, accessories and sleepwear company. They have a number of offerings across these categories, including silk sheets, duvet covers, body pillows, pajamas, and fashion and hair accessories. Silk sheets and pillowcases come in 19, 22, and 25 momme weights. This company is based in China, with all items shipping directly from (we assume) a silk factory. This brings a level of complication when it comes to shipping, returns, and customer service.

    The THXSILK 22 momme pillow comes in a lightweight satin and plastic envelope package with a see-through front (to view color) and a two-snap closure.

    THXSILK Price

    THXSILK queen pillowcase retails for $48.99.

    THXSILK Shipping

    The free, standard shipping for a pillowcase can take as long as 15 (FIFTEEN) days in transit once it ships from China (this estimate may be low given the current international shipping issues and delays). We think that could mean at least a month to get your pillowcase. In order to receive expedited shipping (four to eight days in transit, and we think that may be optimistic) you need to pay $15, which brings your total cost up to $63.99. (Alternatively, you could order $80 worth of merchandise to receive “free” expedited shipping). This is where working with a China-based company can be a little tricky and offset the ostensibly “lower” price of the pillowcase. Your item will be shipped using an international carrier, not FedEx or UPS.

    Bottom line: if you want your pillowcase in a reasonable timeframe, you are going to have to pay the $15 shipping and hope for the best.

    THSXILK Customer Service

    Similar to shipping, working to obtain customer service from a China-based company may prove difficult. THXSILK offers an email option, but no way to call the company and speak to an individual with questions or issues. There is no swatch sample program.

    Our Recommendation: Mulberry Park Silks

    A pure mulberry silk pillowcase Mulberry Park Silks is a better value than THXSILK for a number of reasons. While both are equal in terms of quality of silk used, Mulberry Park Silks offers a far more comfortable envelope closure that won’t poke you while you sleep, or break.

    Now let’s discuss price, shipping, and customer service. It appears that THXSILK is more competitively priced than Mulberry Park Silks. However -- and this is very important -- you will have to pay a $15 shipping charge to receive your pillowcase in less than a month or so. At Mulberry Park Silks, your items are shipped from our Connecticut warehouse via well-established courier companies. There is no mystery, and no chance of an international delay.

    Most importantly, we are a U.S. based company that is committed to the finest customer service. You can email or call us with any question or concern. If you want to speak with someone, our design team is available. We will even send you swatches to review at home before you purchase your silk items. Your experience as a valued member of the Mulberry Park Silks family matters to us personally and we take great pride in serving our clients.
