What quality control looks like in practice

Common questions
Which payment methods do you accept?
We accept bank wire transfer for most wholesale accounts, with card and digital payment options available for samples and smaller orders. Established accounts can apply for credit terms after a trading history has been established.
Do you offer private label or OEM production?
We do. Private label covers artwork, bottle and closure choice on existing formulations. OEM and ODM work goes further into housing, tooling and exclusive development, with confidentiality agreements in place before any formulation detail is shared.
What shelf life should we plan around?
Unopened e-liquid is typically stable for around two years when stored cool and away from direct light, and device batteries lose capacity on a similar curve. We print manufacture dates and batch codes on every unit so stock rotation is straightforward.
