Plugs and Tunnels for Stretched Lobes
Plugs and tunnels are the jewellery of stretched lobes. A plug is solid and fills the stretched hole; a tunnel is hollow, so you can see through it. They come in a wide range of sizes and materials, and they belong in a healed, stretched lobe, not a fresh piercing. Here is how plugs and tunnels work and how to choose them.
Vanhess sells piercing jewellery in Coquitlam; we do not perform piercings. Get pierced at a professional studio, then use this guide to choose your plug or tunnel jewellery.
Plugs vs tunnels
Both plugs and tunnels sit in a stretched lobe, held by a flared edge or by an O-ring or screw-fit design. A plug is solid, so it shows a solid face or a design; a tunnel is hollow through the middle, giving that distinctive see-through look. Styles include single-flare (one flared edge, held by an O-ring), double-flare (flared both ends, for fully healed stretches), and screw-fit. Which you choose is a matter of look and how healed and stable your stretch is.
Sizing and safe stretching
Stretched sizes are measured in larger gauges or in millimetres, and you wear the size your lobe has actually been stretched to. Stretching should be done gradually and only on a healed lobe, never forced, since going too fast or too big can tear the tissue or cause a blowout. Vanhess sells plugs and tunnels for lobes that are already stretched; for the stretching process itself, work with a professional piercer who can guide safe sizing and timing.
Gauge and size
| Style | What it is |
|---|---|
| Solid plug | Fills the stretched hole with a solid face or design |
| Tunnel | Hollow through the middle; see-through look |
| Single-flare | One flared edge, held by an O-ring |
| Double-flare | Flared both ends, for fully healed stretches |
Our sizing and gauge guide explains these numbers.
Styling
Plugs and tunnels are a bold, expressive style. A tunnel frames whatever is behind the ear; a solid plug can show a stone, a pattern, or a simple polished face. Materials range widely, and the size itself is part of the statement. Coordinating a pair and choosing a finish that suits your other jewellery keeps the look intentional.
What to check when buying plug or tunnel jewellery
Before you buy, confirm a few things so the piece fits and heals well:
- Gauge match. Buy the same gauge as your piercing, usually larger sizes, measured in mm for a plug or tunnel. Too thin and it moves in the channel; too thick and it will not fit.
- Smooth through the piercing. Choose threadless or internally threaded jewellery so nothing rough passes through the channel. Externally threaded posts drag screw threads through and irritate it.
- Material. Implant-grade titanium (ASTM F-136) or solid nickel-free gold only. Skip anything plated or unmarked.
- Size. Stretched sizes are measured in millimetres or large gauges; wear the size your lobe is stretched to, never force a bigger one.
- Finish. The piece should feel glass-smooth, with no rough edges or casting pits that can snag tissue.
Style and gemstone options
Plugs and tunnels come in many materials and finishes, from gold-tone and steel to glass and natural materials, plain or gem-set. For a stretch that is still settling, smooth, inert materials such as implant-grade titanium or glass are the safest. Choose the exact size your lobe is stretched to, and keep a plug or tunnel in to maintain the stretch, since large stretches can shrink if left empty.
Common mistakes to avoid
- Changing too early. Swapping jewellery before the piercing is fully healed is the top cause of bumps and setbacks. Wait for your piercer's go-ahead.
- Cheap or plated metal. Nickel and worn plating cause most "my piercing is reacting" problems. Stay with implant-grade titanium or solid gold.
- The wrong size. A post or ring that is too long, too short, or the wrong gauge moves, snags, or presses. Match your gauge and get the length or diameter right.
- Over-cleaning. More than a twice-daily saline rinse, or using alcohol and ointments, slows healing rather than helping it.
- Sleeping on it or knocking it. Pressure and snags are a common cause of irritation, especially in the early weeks.
Aftercare in brief
Whatever you wear, a healing piercing needs the same simple routine: clean it once or twice a day with sterile saline, keep your hands off it, do not twist or remove the jewellery, and leave it in until a professional says it is healed. Stay out of pools, hot tubs, and lakes, and avoid knocks and sleeping on it in the early weeks. Most trouble comes from cheap metal or the wrong size rather than too little cleaning, so the jewellery you choose matters as much as the routine. Our aftercare guide has the full method, and our guide to bumps versus infection covers what to watch for.
Key Takeaways
- Plugs are solid and tunnels are hollow; both are jewellery for stretched lobes.
- Styles include single-flare (O-ring), double-flare, and screw-fit designs.
- Stretched sizes are measured in millimetres or large gauges; wear your actual stretched size.
- Stretch gradually with a professional and never force a size; Vanhess sells jewellery for healed stretches.
Frequently Asked Questions
What is the difference between a plug and a tunnel?
A plug is solid and fills the stretched hole, showing a solid face or design; a tunnel is hollow through the middle, so you can see through it. Both are worn in a stretched lobe and come in single-flare, double-flare, and screw-fit styles.
How are plug and tunnel sizes measured?
In larger gauges or in millimetres, reflecting the diameter of your stretched hole. You wear the size your lobe has actually been stretched to. Never force a larger plug in; going too big too fast can tear the tissue.
Can I stretch my ears with plugs?
Stretching should be done gradually, only on a fully healed lobe, and ideally with a professional piercer guiding the timing and sizes, not by forcing a bigger plug in. Vanhess sells plugs and tunnels for lobes that are already stretched to a given size.
What material is best for plugs and tunnels?
For a stretch that is still settling, smooth inert materials such as implant-grade titanium or glass are safest. Once a stretch is well healed, a wider range of materials and finishes is fine. Keep jewellery in, since large stretches can shrink if left empty.
