Implantium™ titanium flatbacks
Once you try Implantium™, you never go back.
Our flatbacks are made from F-136 implant-grade titanium, with threads three times longer than usual and a flat quatrefoil back, so you can sleep, shower and train in them and stop thinking about your earrings altogether.

What makes it Implantium™
Made differently, down to the post.
From the front, a lot of flatbacks look alike. These are the parts you can't see in a photo, and the reason ours stay in.
- 1
F-136 implant-grade titanium
The same specification used for surgical implants, and nickel-free.
- 2
Threads three times longer
So the front catches first time when you're putting it in at home in the mirror.
- 3
A flat quatrefoil back
It sits flat against your ear, so there's nothing to dig in when you sleep, and it looks pretty from behind too.
- 4
PureTone™ bright silver
Our silver pieces are platinum-plated on the front for a bright silver finish instead of the grey of plain titanium, and the post stays bare titanium.
Implantium™ is only available at Smoothie London.

Before you ask
The questions we actually get.
Are they sold as a pair?
No, our Implantium™ studs are sold as singles, so you can buy exactly what you need, whether you're stacking, replacing one side or mixing pieces.
What post length do I need?
Most people wear a 6mm or 8mm post, and those are our defaults. The quiz will point you to the right one, and if you're still not sure, our Find Your Post Size Kit has five posts so you can try them at home.
I have sensitive ears. Will these work for me?
Implantium™ is implant-grade titanium, ASTM F136, the same specification used for surgical implants, and it's nickel-free. On our silver pieces the post is raw titanium and only the head is plated, so the part in your piercing is bare titanium.
Can I really sleep, shower and work out in them?
Yes, that's what they're made for. The flat back sits flush, the front screws on, and the titanium doesn't tarnish.
What's the warranty?
Lifetime against tarnishing on Implantium™ titanium and PureTone™ stainless steel, and one year on stones, breakages and plating.
How does delivery work?
Every order ships in letterbox-sized packaging, so it goes straight through your door with no waiting in for a courier.
