Questions, answered

Key details before you order.

Everything you might ask

1. Is this in stock?

If the Add to cart button is live, it is physically in our U.S. warehouse, counted, inspected, and ready to ship. Sold-out pieces return with the next release.
2. What will the delivery actually look like?

Your order travels inside an outer carton with no product wording, and a neutral name on your billing statement. What is inside is the SIN box itself: matte black, gold-foil logo, magnetic close. The discretion is on the outside; the reveal is yours alone.
3. What if I am not satisfied?

You are covered by our 30-Day Money-Back Guarantee, and yes, it applies even if you have opened the case and tried every piece. Full refund, we pay the return shipping.
4. What are the materials?

Crystal, PEARL and Keen Bound pieces are premium microfiber on zinc-alloy hardware. BONE pieces are premium PU with genuine leather.
5. We are new to this — is it right for us?

Yes. Every piece is fully adjustable and intuitive to wear, so you set the pace. Start with a single piece and let the rest of the set wait its turn. There is no wrong way to begin, and 30 days to decide it is right for you.
6. When will it arrive?

Every order ships priority to your door in 2–4 business days, with tracking by email. Delivery is free on every U.S. order.
