SIN makes four signature editions. They are not four tiers of the same product — they differ in how many instruments you get, what those instruments are made of, and how openly they are meant to be worn. This is the comparison we would give you in person.
The short version
| Edition | Pieces | Material | Colourways | Price |
|---|---|---|---|---|
| BONE | 11 | PU and genuine leather | Burgundy, Obsidian Noir | $499.99 |
| PEARL | 6 | Microfiber | White / Ivory Pearl | $329.99 |
| KEEN BOUND | 4 | Microfiber | Burgundy, Obsidian Noir | $299.99 |
| CRYSTAL | 6 | Microfiber | Crystal Red, Obsidian Noir | $219.99 |
All four hardware sets are high-grade, hypoallergenic zinc alloy. All four arrive in a locking collector case with every piece seated in its own fitted recess.
BONE — the full case
Eleven instruments in a locking case that measures 79 × 44 × 13 cm closed, and opens flat to 79 × 59 cm. It is the largest thing SIN makes, and it is the only edition where you are unlikely to find yourself wanting a piece it does not include.
Choose BONE if you want the complete range in one case, you prefer leather, and you want an object with presence when it is open on the bed. The two colourways — Burgundy and Obsidian Noir — hold identical contents, so the decision there is purely colour.
PEARL — worn as jewellery
Six pieces in ivory and pearl, in a white collector case measuring 511 × 257 × 48 mm. PEARL is the edition people wear where they can be seen: the collar passes as a choker, the cuffs as bracelets.
Choose PEARL if you want something that does not announce what it is, or if leather feels heavier than what you are after. Its pieces are also sold individually — wrist and ankle restraints, the neck control collar, the blindfold — if you would rather begin with one.
KEEN BOUND — the most restrained
Four pieces in champagne gold, in a keyed presentation case. KEEN BOUND is deliberately the smallest set: wrist restraints, ankle restraints, a neck control collar and a torso restraint belt that anchors the rest.
Choose KEEN BOUND if you want a considered few pieces rather than a full case, and you like the champagne gold against Burgundy or Obsidian Noir.
CRYSTAL — the way in
Six pieces arranged around a single sculpted rose, in a lacquered collector case, in Crystal Red or Obsidian Noir. At $219.99 it is the most accessible full case SIN makes, and nothing about the finish steps down to get there.
Choose CRYSTAL if this is your first case and you would rather start with six matched pieces than with one piece bought alone.
What is the same across all four
- A locking collector case, with each piece in its own recess
- High-grade, hypoallergenic zinc-alloy hardware
- Shipping at $9.95, free over $199, in discreet outer packaging that names nothing
- 30 days to return a set — opened is fine
Still deciding
If you want everything, in leather, in one case: BONE. If you want to wear it openly: PEARL. If you want a few pieces, chosen carefully: KEEN BOUND. If this is the first one: CRYSTAL.
Or compare all the complete bondage sets together, where you can compare them side by side.
If you would rather build up piece by piece than buy a case, every component is listed in the BDSM gear range.
