The part that rescues a dropped pen

The Innokin Prism T18 II tank is the sale that saves a kit: a complete replacement top-end for the T18 II pen with a 1.5ohm coil, a spare, the magnetic cap and a full o-ring set in the box. Single units, three colours.

Nobody plans to buy one. Glass meets pavement, and the counter that has this boxed keeps a customer the counter without it loses to a whole new kit somewhere else.

  • Complete top-end: tank, coil, spare, magnetic cap, o-rings
  • The magnetic cap that keeps pocket fluff off the tip
  • Rescues a T18 II kit for a fraction of replacing it
  • Runs the shared T18/T22 coil line

The economics of the rescue sale

Replacement tanks turn slowly and matter anyway: one or two units held against the local base of T18 II kits is service stock, not a profit line. The payoff is the relationship, plus the T18/T22 coils that tank keeps consuming for another year or two. The Innokin wall earns its keep through exactly this kind of follow-through.

Like the rest of the accessories shelf, it should be ordered alongside kits rather than on its own; a tank without a local pen base is a shelf ornament.

Fit, capacity and the cap

The tank fits the T18 II pen and holds the TPD-standard 2ml. Its party trick is the magnetic cap, which snaps over the drip tip in a pocket and quietly prevents the fluff-on-the-mouthpiece complaint every MTL counter knows. Coils are the shared T18/T22 line, so no new consumable holding is needed. It is not a fit for the T18E or T20S pens, which run their own tanks; check the pen before selling the glass.

Frequently asked questions

How is the Prism T18 II tank sold at wholesale?
In single units, each boxed with a fitted-spec 1.5ohm coil, a spare, the magnetic cap and an o-ring set. One or two units of holding covers most counters.
Which pens does this tank fit?
The Endura T18 II. The T18E, T20S and T22 pens each run different tanks, so confirm the customer's pen before the sale to avoid a return.
Why stock a replacement tank at all?
Because the alternative is losing the customer. A cracked tank without a replacement available usually becomes a new kit bought elsewhere, along with all its future coil trade.
What does the magnetic cap do?
It clips over the mouthpiece in a pocket or bag, keeping lint and dust off the drip tip. Small feature, but it answers a complaint MTL pen owners actually make.
