The Spike Circular Barbell Horseshoe is a circular barbell horseshoe, featuring a single sharp spike top. The open horseshoe shape means each ball end screws onto the bar, so it's easy to resize, swap out, or clean. Either wear it in lip, labret, nose, septum, daith, rook, tragus, conch, orbital, helix, ear lobe, ear, or oral piercings. In a lip or labret piercing, the open ends sit close to the skin, which helps keep it comfortable when you're talking or eating. It's an easy way to bring in the detail without drowning out simpler pieces.
Implant grade titanium, ASTM F136, is the material behind this piece, the same standard used in surgical implants. That means it's hypoallergenic, nickel-free, and safe for sensitive skin, whether your piercing is brand new or years old. It can be safely sterilised, resists corrosion, and stays lightweight without sacrificing strength.
It comes in 16 gauge; diameters from 6mm to 14mm. Full options are listed above the Add to Cart button. Check the size guide first if you're not sure what you're currently wearing.

FAQs
Is solid ASTM F136 Implant Grade Titanium safe for a new piercing?
Yes, you're covered, whether it's fresh or still healing. It's made from solid ASTM F136 implant grade titanium, the medical-grade standard piercers recommend for this stage. It's hypoallergenic and nickel-free, so you don't have to worry about a surface coating wearing away and exposing unknown metals underneath. It's a suitable choice for sensitive skin and people with metal allergies.
What size does this come in?
It comes in 16 gauge, the standard thickness for this type of jewellery. Diameters range from 6mm to 14mm to suit different piercings. Full options are listed above the Add to Cart button. Check the size guide if you're not sure what you're currently wearing.
Which piercings can I wear this in?
You can wear this in lip, labret, nose, septum, daith, rook, tragus, conch, orbital, helix, ear lobe, ear, and oral piercings. Check with your piercer if you're not sure it'll work for your specific placement or anatomy.
How do I clean and care for it?
A saline solution or Pheenix Piercing Spray is all it needs. Skip the alcohol, peroxide, and harsh chemical cleaners, since they'll dull the finish over time. Titanium won't corrode or discolour with normal wear.
