Premium microfiber on zinc-alloy hardware. The rose gag is silicone. The chain is set with crystal pavé, gold on the red set and silver on the black.
The case14.4 × 13.6 × 3.9 in · 7.7 lb
A rigid wood-fibre shell with gold latches, a center lock and two keys on a gold ball chain. Black egg-crate foam in the lid, a fitted tray below. 14.4 × 13.6 × 3.9 in. The full set weighs 7.7 lb.
Fit and adjustabilityOne size, adjustable
The cuffs and the collar close with a flap pressed onto two studs, and the blindfold and rose-gag straps buckle, so the same set fits both partners. There is no size to choose. If you can wear a watch, it fits.
CareWipe clean
Wipe with a soft, barely damp cloth and let every piece dry before it goes back into its recess.
Questions, answered
Key details before you order.
Everything you might ask
Is this in stock, and when will it arrive?
Yes. Every set is in our U.S. warehouse, counted and inspected. Delivery takes 1 to 3 business days, guaranteed and free, with tracking by email.
What will the package look like when it arrives?
An outer carton that carries our logo and no product wording, with a neutral company name on the label. Inside it is the SIN box, matte black with a gold-foil logo and a magnetic close, and inside that the locking case with the set laid in its tray.
What shows on my card statement?
A neutral company descriptor, such as SP Holdings LLC. The product is never named on the statement.
What if it is not right for us?
You have 30 days from delivery, and that includes after you have opened the case and tried every piece. Email support@sinpremium.com with your order number, we send a prepaid label, and the full price goes back to your card within 5 to 10 business days of the return arriving. We pay the return shipping and there is no restocking fee.
What are the pieces made of?
Premium microfiber on zinc-alloy hardware, with crystal-set chain: gold on the red set, silver on the black. The rose gag is silicone. The case is a rigid wood-fibre shell with gold fittings, and it locks with two keys.
We are new to this. Where do we start?
With one piece. Most people start with the wrist cuffs and let the rest of the set wait its turn. Agree on a word that stops everything and keep it within reach. There is no wrong way to begin, and you have 30 days to decide it is right for you.
Is there a warranty beyond the 30 days?
Yes. Every SIN piece is covered against faults in materials and workmanship. If a stitch fails, a rivet lets go or hardware breaks in normal use, send a photo to support@sinpremium.com and we replace the piece.
Which payment methods do you take?
Visa, Mastercard, American Express, Discover, Apple Pay and Google Pay. Checkout is hosted by Shopify and is PCI DSS Level 1 certified. We never see your card number.

Every piece laid around a single rose, in a locked case you open together.

Customer Reviews
Overall rating: 4.9 / 5 from 185 reviews.
The rose in the center is what makes this set memorable. It gives the whole case a point of view instead of looking like six accessories arranged in foam.
We have tried smaller couples kits before and they usually get forgotten. Crystal has enough variety that we keep finding a reason to open the case again
I like that the cuffs and collar can adjust for either of us. It made the set feel like something we could both use instead of being made for one person
I bought it partly because the red and gold look caught my attention. It ended up being more useful than I expected and we have already gone back to it
I am not into anything super extreme and I still liked this set. It can be as simple or as adventurous as you want depending on what you choose from the case
Date nights have gotten pretty repetitive for us and this gave us something new without needing a whole plan. We just opened the case and picked a couple of pieces
We have used it more than once already because there are different ways to combine the cuffs, collar and blindfold. It does not feel like a one night product
I normally get embarrassed ordering this kind of thing but the whole process felt private. The packaging and the way the set is presented made a big difference
