Double Sonic

Measure for a ring:

1. Wrap a strip of paper, string, or non-stretchy ribbon around the base of the finger.
2. Mark where the end meets the paper/string.
3. Measure that length with a ruler (in mm). This is the finger’s circumference.
4. Use a ring size chart to convert circumference to ring size.

Measure for a cuff/bangle:

1. Ring your thumb across your palm as if putting on a bracelet.
2. Wrap a tape measure or string around the widest part of your hand (usually across the knuckles).
3. Record that measurement in mm — this is your hand circumference. Compare this to our listed sizes.

SKJ jewelry is designed to be both sensorial and enduring, but proper care is essential.

We recommend:

• Avoid contact with water, perfumes, lotions, and chemicals
• Remove jewelry before showering, swimming, or exercising
• Store pieces in a dry, soft-lined environment
• Clean gently with a soft cloth

Some pieces incorporate moving or tactile elements—handle them with care to preserve their integrity.
