Lobe Cuffs aka ear sleeves in surgical steel. They are designed to wrap around the lobe. The size listed is the minimum size stretch required but they can fit in larger stretches just as easily.
If you have very thick lower lobes they might not fit as well around the lobe as on thinner lobes so bear this in mind. Measure the thickness of your lobe. The internal diameter of these cuff is about 5mm. Do not wear if the cuff is too tight.
Unless clearly stated otherwise,
the price is for one piece, not a pair.
