Promeed 23 Momme Mulberry Silk Pillowcase with Zipper (Queen)
Best for: The buyer who wants full-weight mulberry silk with a zipper, prefers buying direct with a real return window, and does not need Amazon delivery speed.
A 23-momme 6A mulberry case with a hidden zipper, sold direct with free US shipping and a 60-day return window — the Slip and Blissy weight class at ZIMASILK money.
Promeed is a silk-focused brand, with a Spokane, Washington address listed on its site, that sells direct rather than through Amazon. It also sells pillows and comforters. The pillowcase is 23-momme 6A mulberry silk on both sides — a hair above the 22-momme standard that Slip, Blissy and ZIMASILK share — closed with a hidden zipper and shipped with a mesh laundry bag so it can go in the machine on a cold delicate cycle. It carries OEKO-TEX Standard 100 certification and comes in Standard, Queen and King in a wide colour range. Because you buy from the brand, returns are 60 days and free by mail — longer than the usual marketplace window. The trade-offs: no Prime-speed delivery, a review base that lives on Promeed's own site rather than a marketplace, and the '6A+' grading is Promeed's label — 6A is the top industry grade and the plus is marketing.

How our prices work
We show the price at our recommended retailer as at our last check of that offer (2026-09-17) and, when Amazon reports one, its list price for comparison. Amazon prices come from Amazon's own product data service and are refreshed twice a day; each one shows the date and time Amazon gave it, and one older than 24 hours is replaced by “Check price”. Other retailers' prices are checked by hand and show the date of that check. Retail prices move constantly, so the price on the retailer's own page at checkout is the one that applies.

Frequently asked questions
Is 23 momme better than 22 momme?
Marginally. Momme is silk density; 22 is the weight most premium cases use, and 23 is one step heavier — slightly more silk per square metre, which shows up as a touch more body and durability rather than a different feel. It is not a reason to pick Promeed over a 22-momme case on its own; the zipper, the certification and the return terms are.
Promeed vs ZIMASILK?
Similar money for similar silk. ZIMASILK is 22 momme sold on Amazon with Prime delivery; Promeed is 23 momme sold direct with free shipping and a 60-day free return window. If you want it in two days, ZIMASILK. If you want free returns and to buy direct from the maker, Promeed.
Promeed vs Blissy?
Both are 22–23 momme 6A mulberry with OEKO-TEX certification. Blissy charges noticeably more for the bigger brand name; Promeed matches the spec, adds a slightly heavier weave and buys you the direct 60-day return terms for less. Pay for Blissy only if the name matters to you.
Can I machine wash it?
Yes — cold water, delicate cycle, inside the mesh bag that ships with it, with a silk-safe detergent, then air dry. That is Promeed's own care guidance, and it is friendlier than the hand-wash-only instruction on some competitors.
What does '6A+' mean?
6A is the highest standard grade for mulberry silk thread. The plus sign is Promeed's own label, not an industry tier — treat it as 6A. That is still the same grade Slip, Blissy and Mulberry Park quote.
