This is a popular gauge size.
Even for those who have pierced their ears with 14G, if you haven't worn earrings for a while, the piercing hole may have shrunk, so 16G is recommended.

If you pierced your ears with a 14G needle, please choose 14G.

Piercing hole thickness +1mm

Since it is easier to attach and detach parts and clean the barbell, we recommend choosing a size that is 1mm thicker than the thickness of your piercing hole. Although it varies from person to person, 7mm is generally popular for outer conch piercings.

What are outer conch piercings?

Outer conch earrings are earrings worn on the flat cartilage area at the upper part of the ear. As it gets closer to the edge of the ear, it becomes the area called the helix, so it is positioned more towards the center. Because the earrings are easily visible and various designs of earrings can be easily worn, they are popular not only among younger people but also among those in their 40s and 50s.

Where is the cute spot for outer conks?

The outer conch is recommended for the central part of the flat cartilage above the ear.
By piercing the hole as close to the center as possible, you can wear three-dimensional or larger designs of earrings, expanding the range of your earring fashion.

What is the pain like when opening the outer conch?

The outer conch is a firmer cartilage area, and to prevent issues such as the needle not penetrating, it is common to use a needle rather than a piercer to pierce it.
Therefore, when opening, it tends to be slightly more painful compared to soft earlobes and the like.
Also, if you are not accustomed to self-piercing with a needle, we recommend having it done at a clinic.
*If opened at a clinic, anesthesia may be administered before the procedure.

How to open it without making a mistake?

Self-piercing with a needle tends to be more difficult and prone to failure compared to self-piercing with a piercer.
Positions where tasks like outer conks are difficult may result in the needle not piercing properly, causing misalignment or slanting, and may not go well.
To avoid such mistakes, we recommend having a pre-consultation at a trusted clinic and having the procedure done safely with appropriate equipment.

*Piercing is a medical procedure. We basically recommend having it done at a clinic.

What are the recommended first earrings?

First, it is important not to cause any irritation or strain to newly pierced earlobes.
For that reason, you should avoid heavy items with snag-prone designs or large motifs.
It is also important to choose materials that are compatible with your own metal allergy type.

For design, lightweight, compact, and snag-free items are recommended.
For the length of the barbell, it is recommended to choose a length that is "2mm longer than the thickness of the piercing hole" to accommodate swelling until the piercing hole stabilizes.
If you choose a barbell that is the exact size while in an unstable condition, there will be no gaps for dirt or secretions to escape, leading to troubles such as inflammation, pus, and granulomas.
However, items that are too long can cause unnecessary snagging after the swelling goes down, so we recommend piercing hole size + 2mm.

What earrings are recommended for outer conch?

It varies depending on the shape of the ear and the position of the piercing hole, but generally, it can accommodate quite large sizes, so almost all earrings can be used for parts.
*For hoop types, please check the inner diameter of the earrings according to the position of the piercing hole.
