Fit & post size
Pick your length by piercing stage.
Healed piercings: 6mm. For lobe, upper lobe, helix, forward helix and tragus.
Conch, or new and still-healing piercings: 8mm. For any conch, and all new or healing placements.
The post. 16g (1.2mm), internally threaded, with a smooth flat disc on the back. It's a touch thicker than most butterfly-back studs, so it might feel snug at first.
Betty U-Hoop? There, 6mm or 8mm is the hoop size. Our model wears the 8mm in her lobe.
Single or pair? Single is one earring, pair is two.
This is a guide only. If you need a hand, email support@byraejewellery.co.uk.
Why it lasts
Implant-grade titanium (ASTM F136). One of the most skin-friendly metals going. Hypoallergenic, nickel-free and properly lightweight.
Made for real life. Shower, swim, sweat and sleep in them. No green marks, ever.
Flat back, no butterfly. A smooth disc sits flush behind your ear, so nothing digs in on the pillow.
Delivery, returns & guarantee
Free UK delivery over £60. Order before 2pm Monday to Friday and it goes out the same day.
Lifetime breakage guarantee. If it breaks, email hello@byraejewellery.co.uk and we'll sort it.
Returns. 14 days on non-earring pieces. Earrings are non-refundable for hygiene reasons, and outlet and last-chance pieces are final sale.

How to put them in
Three easy steps
-
01
Unscrew the top
Wash your hands, then twist the top off the post, anticlockwise.
-
02
Post in from the back
Push the post through your piercing from behind your ear, so the flat disc sits against your skin.
-
03
Screw it back on
Hold the disc still and twist the top on, clockwise, until it's snug. Done. Now forget about it.
Tip: do it over a towel, not the sink. The tops are tiny.
Your questions, answered
Will they fit my piercing?
Posts are 16g (1.2mm), standard for flat back jewellery but a touch thicker than some traditional butterfly-back studs. If that's all you usually wear they might feel snug at first. A taper tool or professional piercer can help fit these for you. For the post length click 'find your perfect fit' above.
Which length do I need?
It depends on your piercing stage and individual anatomy. We recommend: Healed piercings: 6mm (lobe, upper lobe, helix, forward helix and tragus). Conch, or new and still-healing piercings: 8mm. On the Betty U-Hoop, 6mm or 8mm is the hoop size (see the size guide)
This is a guide only. If you need a hand, email support@byraejewellery.co.uk.
Can I actually sleep in them?
That's exactly what they're made for. The smooth flat back means no post or butterfly digging in, so they're comfy for sleeping, headphones and workouts.
Can I shower and swim in them?
Yes. Shower, swim, spin, repeat. They're waterproof and sweatproof and won't turn your ears green.
Single or pair?
Single is one earring, pair is two. Mixing singles is the easiest way to build your stack.
What is implant-grade titanium?
Nap Stacks are made from ASTM F136 implant-grade titanium, one of the most skin-friendly materials used in piercing jewellery. Lightweight, strong and what piercers use - so great for sensitive ears.
What if one breaks?
We make jewellery to be lived in, so we stand behind it. Our lifetime breakage guarantee covers breakages, including chains, clasps and stones. Email hello@byraejewellery.co.uk and we'll sort it.
Are earrings refundable?
Earrings are non-refundable or exchangeable for hygiene reasons. Everything else has 14 days as per our refund policy.
