Off-Stamp X-Cube 25K Kit — Overview
The Off-Stamp X-Cube 25K Kit is a modular disposable vape system powered by Lost Mary technology, pairing a reusable 1,100mAh Smart Charging Device with swappable prefilled pods. Unlike traditional disposables where you throw away the entire device, the X-Cube lets you keep the battery and screen — just replace the pod when it runs dry. Each pod holds 18mL of 50mg salt nicotine e-liquid and delivers up to 25,000 puffs through a dual mesh coil. For a complete breakdown of how the system works, see our Off-Stamp setup and usage guide.
What separates the X-Cube from other modular vapes is the 2.25-inch TFT smart screen with customizable animations, 3 power modes (Light, Normal, Turbo), and 2-level adjustable airflow — features you'd normally find on a refillable pod mod, not a disposable. The pod also packs its own 100mAh internal battery, meaning it works as a standalone device even without the charging dock attached. If you're weighing this against other modular systems, our NERA 70K vs X-Cube 25K comparison breaks down the key differences.

Why Choose the Off-Stamp X-Cube 25K Kit
Modular Design Saves Money Long-Term
The X-Cube's two-piece architecture means you only replace the pod ($19.99) instead of buying a whole new device each time. The 1,100mAh charging dock is built to last through dozens of pod swaps. Over time, switching to replacement pods instead of buying full kits cuts your cost per puff significantly — especially if you vape daily.
Pod Works Without the Dock
Unlike most modular systems where the pod is dead without the battery base, each X-Cube pod has its own 100mAh internal battery. Pop it off the dock and it still fires for 200-300 puffs on its own — enough for a quick errand or night out without carrying the full kit.
2.25" TFT Screen with Custom Animations
The smart screen shows real-time battery level, e-liquid status, and puff count — but it also lets you cycle through animated wallpapers using the side button. It's the largest screen in the Off-Stamp lineup and one of the sharpest among all disposable vapes in its price range.
3 Power Modes for Different Preferences
Light mode stretches puff count to the maximum 25,000 with a cooler, smoother draw. Normal mode balances flavor and longevity. Turbo mode ramps up wattage for warmer, denser hits — ideal for fruit and dessert flavors that benefit from extra heat. The actual puff count will vary depending on which mode you use most often.
Adjustable Airflow with MTL Focus
The 2-level airflow switch on the side gives you a choice between a tighter MTL draw (closer to a cigarette) and a slightly looser restricted MTL. Neither setting is wide-open DL — this device is tuned for mouth-to-lung vapers, which matches the 50mg nicotine strength well.
Available Flavors
- 🔥 Bangin' Peach — ripe peach with candy-sweet finish
- 🔥 Florida Sherbet — citrus blend with creamy sherbet base
- 🔥 Dragon Strawnana — dragon fruit, strawberry, banana fusion

- Blue Razz Ice — blue raspberry with cooling menthol
- Pineapple Passion Orange — tropical trio blend
- Rocket Popsicle — multi-fruit popsicle with icy finish

Frequently Asked Questions
Is this product authentic?
Yes. VapesOnlineShop is an authorized US distributor. Every Off-Stamp X-Cube 25K Kit ships from our Memphis, TN warehouse with original sealed packaging. Off-Stamp products include a verification code you can check on the brand's website.
How long does shipping take?
Orders placed before 2 PM CST ship same day from Memphis, TN. Standard delivery takes 3-5 business days within the continental US. Orders over $80 qualify for free shipping. Adult signature (21+) required on delivery.
Can the pod be used without the charging device?
Yes. Each X-Cube pod has its own 100mAh internal battery, so it fires independently for approximately 200-300 puffs without the dock attached. This makes it convenient for short trips — just detach the pod and go. The charging device is needed to recharge the pod and access the full 25,000 puff capacity.
How does the X-Cube 25K compare to the X-Cube 35K?
The X-Cube 35K Kit (Crystal Edition) offers 35,000 puffs with a larger e-liquid capacity and updated crystal design. The 25K Classic Cube uses the same modular system and charging device at a lower price point. If you already own the 25K dock, note that 35K pods are not cross-compatible — they use a different pod form factor. Read our X-Cube 35K review for the full comparison.
What makes Off-Stamp different from regular disposables?
Off-Stamp is backed by Lost Mary technology but built around a modular, eco-friendlier concept. Instead of throwing away the entire device (battery, screen, electronics) when the liquid runs out, you keep the charging device and only replace the pod. This reduces electronic waste and lowers your per-puff cost over time. See our full Off-Stamp X-Cube review for an in-depth look at the platform.
⚠️ WARNING: This product contains nicotine. Nicotine is an addictive chemical. You must be 21+ to purchase vaping products. VapesOnlineShop is an independent authorized US distributor and is not affiliated with Off-Stamp or Lost Mary.
