I loveeee these earrings they have been in for ages and have had no issues, they helped to heal my difficult piercings in the second lobe
A quatrefoil flat back sits behind the ear and the front screws on. Nothing to poke, nothing to catch, nothing to take out at night.

“The only materials I recommend for piercings are implant-grade, especially titanium. With cheaper alternatives, you never really know what metals are hidden beneath the plating, and that uncertainty can lead to complications”

Loved by 24,000+ ears.
A flatback stud with two bezel-set stones suspended on fine chains of different lengths. Designed for vertical helix or hidden helix placement - the chains drape down for movement and dimension.
Please note: 1.2mm is a standard cartilage gauge and may be too thick for most lobe piercings, which are typically pierced at 0.8mm or 1.0mm.
8mm - standard for lobes and most fresh piercings.
6mm - a snug fit for thinner cartilage placements (helix, tragus, flat). Fully healed and want it flush? Choose 6mm.
Internally threaded, with threads 3x longer than standard so the front catches first time at home. Sold as a single - choose Pair above if you want two.
Fresh piercing? Posts often need downsizing once the swelling goes. Ask your piercer when.
Same-day dispatch on orders placed Monday to Friday before 2pm.
Letterbox-sized, so it goes through the door. You do not need to be in.
Lifetime warranty against tarnishing on Implantium™ titanium and PureTone™ steel. One year on stones, breakages and plating wearing off.
Implantium™ is our name for ASTM F-136 implant-grade titanium - the alloy standard written for surgical implants, and the metal piercers ask for by name. Nickel-free. Hypoallergenic. Never turns green.
"Titanium" on a label can mean several grades. Implantium™ means one, and it is only available at Smoothie.
Gold styles are plated with real gold over the same titanium.

Why it stays in
A flat back behind the ear. Nothing to poke into a pillow.
Swim, sweat, shower. It comes out the same as it went in.
Built to live on you, not in a box.
Implantium™ F-136 implant-grade titanium. Nickel-free and hypoallergenic.
The top twists off the post.
The flat disc sits against the back of your ear.
3x longer threads, so it catches first time. Finger-tight. Done.
Built differently

ASTM F-136 titanium
Our name for implant-grade titanium - the alloy standard written for surgical implants, and the metal piercers ask for. Nickel-free. Never turns green.

Easy at home
Because we're sick of dropping our earrings down the sink. Change them at home in 30 seconds.

Not a plain disc
The flat back is a four-leaf shape, so it looks as considered from behind as it does from the front. Nothing to poke into a pillow.
Before you ask
Yes. A flat disc sits behind the ear instead of a butterfly back, so there is nothing to poke into a pillow.
No. Implant-grade titanium does not fade, rust or discolour. Swim, sweat, shower and sleep in it.
One. Flatbacks are sold as singles so you can mix and match across lobe and helix positions. Choose Pair above if you want two of the same.
8mm is standard for lobes and most fresh piercings. 6mm is a snug fit for thinner cartilage placements - helix, tragus, flat. Tap where it is going above and we will pick for you. Still not sure? Spare posts are £1 each, or £5 for the kit with one of every size.
Our titanium is Implantium™, implant-grade F-136 - the material piercers actually recommend. Nickel-free and hypoallergenic.
Implant-grade titanium is what professional piercers use for healing piercings, but healing depends on more than the jewellery - post length, aftercare and not sleeping on it all matter, and posts often need downsizing once the swelling goes. Ask your piercer when to switch. They know your ear.
Internally threaded, with threads 3x longer than standard so the front catches first time. Twist the front piece onto the post to put it in; gently unscrew it to take it out.
Lifetime warranty against tarnishing on Implantium™ titanium and PureTone™ steel, and a year on stones, breakages and plating wearing off. Message us and we will sort it. Full terms here. Same-day dispatch on orders placed Monday to Friday before 2pm.
A quatrefoil post rather than a plain disc, so it looks as considered from behind as it does from the front.
