HIGHLIGHTS

What makes the v4 different

Four things that decide whether a tank is pleasant to live with for a year, or for a week.
No bending wire, no trimming coil legs. The coil drops straight into the terminals and is captured by a single hex screw.

Indexed airflow

Three detents so the setting you chose stays chosen, even in a pocket.

Quarter-turn fill

Quarter-turn fill

Top-fill bayonet opens in a quarter turn. No threads to cross, no cap to lose.

WHAT TESTERS SAY

"It just works — every single time."

Across 2,000+ builds logged by workshop owners and daily users, the phrases that came up most were quiet, easy to clean, and stays tight in a pocket. The postless deck removed the step people hated most, and the indexed airflow is the feature reviewers did not know they needed until they had it.
  • Rated 4.8 / 5 across 2,000+ builds
  • "Quiet flavour" — most-cited phrase
  • "Easy to clean" — second most-cited
  • "Stays tight in a pocket" — airflow detents
Bench assembly, Shenzhen — each unit is checked by hand before boxing.
BRAND STORY

Made the slow way

We make a small number of things, slowly.

The Era line began as a workshop exercise: how few parts can a tank have before it stops working well? Four years and eleven revisions later, the answer is nine. Each revision removed something — a post, a seal, a step in the assembly — and each removal made the flavour a little clearer.

We do not chase trends or release on a calendar. When a revision is ready, it ships.
  • Eleven revisions across four years
  • Nine parts in the final assembly
  • Every unit individually inspected
Postless deck: terminals replace the traditional two-post bridge.
BUILD DECK

Postless deck

There is no post to wrap wire around and no leg length to guess. The coil drops straight into the terminals and is captured by a single hex screw on each side — tighten, snip the excess, done. First builds take minutes. The tenth looks like the first.
  • No wire bending around a post
  • No measuring coil legs
  • One hex screw per lead, captured and secure
  • Fewer parts to short or loosen
Bottom airflow ring with three indexed detents.
AIRFLOW

Indexed airflow

The bottom airflow ring clicks through three indexed positions — tight, medium, open. Each detent holds, so the draw you set in the morning is the draw you get at night, even after the tank has spent the day in a pocket. The path is short and straight, so flavour stays clean and leaks stay rare.
  • Three indexed positions with detents
  • Stays set in a pocket
  • Short, straight bottom path
  • Leak-resistant by design
Single-coil build, centred for an even, flavour-first draw.
FLAVOUR

Flavour, not clouds

The 24 mm chamber is tuned for taste. A single coil, a centred postless deck and a short airflow path put the vapour on your palate before it has time to cool and flatten. You get dense, clear flavour at a sensible wattage — the kind that makes you slow down.
  • 24 mm chamber tuned for taste
  • Single-coil clarity
  • Centred, postless vapour path
  • Performs at everyday wattages

FAQ

Frequently asked questions

Is this suitable for someone new to rebuildables?
Yes. The postless deck removes the hardest step — trimming and bending coil legs around a post. If you can cut a lead to length, you can build this tank.
What is the minimum order quantity?
Five pieces for stock finishes. OEM colourways and laser engraving start at 200 units.
Which countries do you ship to?
Currently the United States, United Kingdom, Germany, France and Japan. Other destinations can be arranged for orders above 100 units.
Is spare glass included?
Yes. Every retail box contains one spare borosilicate tank and a complete O-ring set.
How is the v4 different from the v3?
The airflow ring now has indexed detents, the fill port is 20% wider, and the deck screws were changed to a coarser thread that is harder to cross-thread.

Buyers consistently praise the indexed airflow and the postless deck. The most common phrases are "quiet flavour", "easy to clean" and "stays tight in a pocket".
M. LinSep 09, 2026

Flavour-first design

The postless deck removes all the guessing. First build took three minutes, and the flavour is noticeably cleaner than my previous tank.
K. OwenSep 09, 2026

Airflow stays put

Indexed airflow is the feature I did not know I needed. It clicks into place and does not drift in my pocket. Top-fill bayonet is fast.
S. PetrovSep 09, 2026

Quiet, solid, easy to clean

Very few parts to disassemble for cleaning. The spare glass in the box is a nice touch. Wish the drip tip had more options.
A. ChenSep 09, 2026

Our shop standard

We have sold through three batches. Returns are near zero. MOQ of 5 makes it easy to test.
