Airflow tuning is the single adjustment that changes how Marvos 4 feels in daily use.
Distributors reviewing their Marvos 4 range usually find that airflow tuning explains most of the variance in results between accounts.

Why airflow tuning matters on the Marvos 4
Restricted airflow suits mouth to lung customers moving from traditional products.
In practice the decision comes down to three numbers: unit cost, freight per unit and the realistic sell through rate for Marvos 4.
Open airflow serves direct lung users who prioritise vapour volume.

Commercial terms
Volume commitments work best when they are structured as a rolling target rather than a single fixed number.
Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.

| Carton (82 units) | Tier 1 | 7-12 days |
| Pallet (1369 units) | Tier 2 | 30-45 days |
