Lost Mary OS5000 Disposable Vape

The OS5000 is the shape people picture when they hear "Lost Mary" — the squared little brick that helped define the 5,000-puff generation. It still earns its shelf space three ways: it is the cheapest genuine device we sell at $8.99, it is the most pocketable thing in the store, and it recharges over USB-C so the tank — not the battery — decides its lifespan. That last point was its quiet advantage over rivals in its generation, most of which died with a third of their liquid unreachable.

The draw is simple and firm — no modes, no screen, no airflow adjuster, just draw-activated firing at 5% (50 mg/mL) salt. That simplicity is the product: nothing to configure means nothing to explain, which is why it remains the device we point at for a first try. At $8.99 against a $25 flagship, it answers "is vaping for me" at a third of the cost of asking with anything bigger.

As a primary device it suits light vapers who prefer restocking weekly to carrying a brick; for everyone else it is the classic backup — the glovebox unit, the travel spare. Stock reflects its veteran status: the catalog runs 14 variants but only 1 are in stock — the selector above shows which, and the footer restock list covers the rest. Details on how it compares to bigger formats live on our cheap disposables shelf.

The OS5000 catalog lists 14 flavors, but as a legacy device it rotates stock hardest of anything we carry — 1 are in stock right now, and the selector above is the live list. If what is up suits you, it is in stock now at $8.99; if you want a compact with a wider live menu, the MO5000 next shelf over currently holds the deeper live menu, including several compact-exclusive originals.
