## Emma's take

Wear it as jewelry, mean it as ownership, lock it your way.

This collar is built to work double duty: ruby crystals and a matte chain that read as jewelry until the working lock tells the real story, a small mark of ownership you can wear anywhere. It's a strong pick if you want that quiet thread of control to follow you past the bedroom, thanks to the 9 to 20 inch adjustable fit. Skip it if you want something ultra-soft against skin, the metal-and-acrylic build reads bold, not plush. Get the most from it by locking it snug and keeping the spare key close.

## Frequently asked questions

## What does the crystal day collar symbolize?

This collar is built to be dual-purpose: ruby red crystals and a matte black chain read as jewelry, while the working lock adds a quiet note of ownership and connection for the bedroom.

## How do I adjust the collar to fit my neck?

The chain adjusts from 9 to 20 inches, so you can wear it snug and secure or looser like an everyday necklace. Lock it at your preferred length with the included key.

## How do I clean the crystal day collar?

Wipe the crystals and chain with a soft, dry cloth after each wear to keep them shining. Skip submerging it in water since that can affect the lock mechanism over time.

## Is the collar safe for sensitive skin?

The collar is made from 50% iron alloy, 40% acrylic, and 10% zinc alloy, so anyone with known metal sensitivities should check the materials before extended wear.

## Can I wear this collar outside the bedroom?

Yes. The design is meant for discreet, anytime wear, subtle enough to double as a bold fashion accessory outside the bedroom.
