Phoebe on our team is a US 7.5. She wears a 38 — a perfect fit.

THE KITTY Runs slightly large

Runs about half a size larger than THE MULE. Order your true size — if you're between sizes, take the smaller one.

THE PUFF WEDGE Runs small

Runs a full size smaller than THE MULE. Order one full size up from your true size.

nou x Tobe

Made for open-toe season.

Crafted in 24K gold-plated sterling silver, the Sirena Double Trouble Toe Ring was designed for your toes but looks just as good as a pinky or midi ring once sandal season takes a back seat.

One size, with an open design that fits comfortably across different toes — no bending or reshaping required, so the stone setting stays exactly as crafted. Open hoop toe ring with an organic, openwork silhouette inspired by natural, fluid shapes, with two central zirconia stones in light blue and peach color that add a subtle touch of color and light.

Each piece is handcrafted by Tobe in her Porto studio using thoughtfully sourced materials and locally made components. No two are exactly alike, and that’s exactly the point.

Made slowly, made by hand, made to be lived in.

objects of affection, vol. 1 — the first in a series of limited releases. once it’s gone, it’s gone.

One size (EU 45, 14.5mm inner diameter) — open design fits comfortably on multiple toes or as a pinky/midi ring — do not bend or reshape to fit, as this can damage the stone setting.
Made for real wear — sterling silver and gold plating may evolve over time with exposure to moisture, sweat, salt, sand, and skin pH
Handmade in Portugal

To preserve your piece for as long as possible, avoid contact with perfumes, sunscreens, chlorine, cleaning products and seawater whenever possible, and store it in a dry place when not worn.
