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 links woven through champagne-gold zinc-alloy plaques, with a gold curb-chain lead and four gold connector chains. The case is a rigid wood-fibre shell, 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.

Customer Reviews
Overall rating: 4.9 / 5 from 175 reviews.
The woven red straps and champagne-gold plaques are what made KEEN stand out to me. It looks more tailored than a typical restraint set.
We have tried plain cuffs before and got bored with them pretty quickly. The waist belt and connector chains give Keen Bound enough variety that we keep coming back to it
I originally chose it because the gold details looked good in the photos. After using it I liked the actual connection system even more than the appearance
The waist belt is the piece that makes KEEN make sense. Once everything can connect back to one anchor, the whole set feels organized instead of random.
We have two kids and our time together is limited. This is easy to pull out when we have a night to ourselves because everything we need is already in the case
We tried the cuffs by themselves first, then added the belt later. The second setup felt completely different even though we were using the same pieces.
I got this for our anniversary because I wanted something we would both remember. The case and gold hardware made it feel like a much more substantial gift
