Slipintosoft makes mulberry silk and cashmere pieces, from sleepwear and bedding to clothing and accessories for women, men and kids, and sends them straight from China.
The figure to plan around is $99: below it, delivery to the United States costs $9.99, and anything picked from clearance or silk lingerie is final sale, so a discount there cannot be undone by a return.
Slipintosoft says all of its silk products carry OEKO-TEX STANDARD 100 certification, meaning they are tested for harmful substances, and that it has worked with silk for more than ten years. Its silk bedding, including pillowcases, duvet covers, comforters and fitted and flat sheets, can be shopped by fabric weight in 19, 22 and 25 momme.
For women, the range spans silk pajamas, nightgowns, robes, kimono robes, blouses, slips and lingerie, plus cashmere sweaters, cardigans, hoodies and coats; plus-size sleepwear and matching couple and family pajamas are also offered. Men's lines include silk boxers, shirts and robe sets, and kids get cashmere knits and baby silk clothes. Accessories run from silk bonnets, eye masks and slippers to cashmere balaclavas, socks and leg warmers, and the site's Silk 101 pages explain silk care, the difference between silk and satin, and how to spot real silk.

More about shopping at Slipintosoft
Final sale
Clearance, silk lingerie and customized pieces are all excluded from returns, so ordering a custom size is a one-way decision. (read Sep 29, 2026)
Customs duties
Any import duty charged on arrival is refunded within 3-5 working days once the receipt is emailed to the store.
International
Most countries are covered, at $12.99 to many of them below the free-shipping line, with FedEx or DHL express as faster options.
Address limits
Parcels cannot be delivered to P.O. boxes or to military APO/FPO addresses, so a street address is needed.
Slipintosoft runs on Shopify, so the discount box sits in the order summary on the checkout page.
The 10% newsletter code arrives by email after the homepage sign-up, which means subscribing before building the cart rather than halfway through checkout.
Look at what the code is paired with: clearance items and silk lingerie are final sale, and customized sizes cannot be returned or exchanged, so a discount on those pieces locks the purchase in.
Keeping the discounted subtotal above $99 also keeps shipping free, which matters because the flat $9.99 fee can swallow most of the saving on a small silk accessory order.

More ways to save at Slipintosoft
Beyond the email sign-up, savings at Slipintosoft come from how an order is shaped.
Grouping silk and cashmere into one basket over $99 removes the delivery charge to the United States, Canada, Australia and the UK.
Choosing sizes carefully pays off too, because sending back 3 or more items can cost a 10-20% handling fee and the buyer covers return postage.
Shoppers abroad who are charged import duty can claim it back by emailing the receipt.
