Sealed for hygiene — cannot be returned once opened

This piece goes through a piercing, so it is sent in a sealed pack with a tamper-evident seal. Once that seal is broken it cannot be returned for hygiene and health reasons. Unopened, it still carries the full 14-day right to cancel. Faults and wrong items are always put right. Read the returns policy.

Positions it is sized for

Suitable during healingNoNot recorded as suitable, on the basis of its material or construction.

We do not give medical advice. Questions about piercing, healing or aftercare belong with a professional piercer or a healthcare professional. Everything on this page describes materials and construction only.

Nickel and reactions

Nickel-safe — tested to UK REACH limits (BS EN 1811).

Meeting the nickel release limit is not a promise that nobody will react. Some people react to other metals or materials — cobalt, chromium, resins and platings among them. If your ears are sensitive, wear a new piece for a short period first and see how it settles.

In detail

The post is 0.9 mm across and 10 mm long — a fraction thicker than our titanium studs, which matters if your piercings healed around a 0.8 mm post. The butterfly clutch grips by friction on the plain shaft; it is the easiest back to put on one-handed and the easiest to lose.

Looking after it

Sterling silver darkens on contact with air. Polish with a silver cloth and store dry between wears.

    Nice weight, clean finish. They do darken after a few weeks but the site says so up front, and a polish sorts it.
