Off Stamp Pods — Every Cube Series Explained & Compared

Off Stamp replacement pods are the consumable half of the X-Cube system — the part you swap when the e-liquid runs out while keeping the same rechargeable dock. Four Cube series are available, each with a different flavor focus and, in the case of Sweet Cube, unique hardware features. All pods are cross-compatible with both the 25K and 35K X-Cube docks. This guide covers every series, explains what makes each one different, breaks down pricing and compatibility, and helps you decide which pods to buy first.

How Off Stamp Pods Work

Every Off Stamp X-Cube pod is a self-contained unit: pre-filled e-liquid, dual mesh coil, mouthpiece, and a 100mAh internal battery — all sealed at the factory. You do not refill them, replace coils, or do any maintenance. When the e-liquid runs out, you pull the pod off the magnetic dock and snap a new one on. The entire swap takes under five seconds.

The key distinction from a standard disposable: the pod is only half the device. The expensive electronics — the 1,100mAh battery, TFT screen, power modes, airflow control — all live in the reusable dock. Buying pod-only replacements is significantly cheaper than buying a new kit every time, which is the entire economic rationale for Off Stamp's modular design.

4 Cube Series at a Glance

All four Cube series share the same physical dimensions, dual mesh coil, and magnetic connector. They are 100% interchangeable on any X-Cube dock. The differences are flavor direction and, in the case of Sweet Cube, a unique dual-tank sweetness control feature.

Series	Flavor Count	Flavor Style	Special Feature	Best For
🟠 Classic Cube	18	Fruit, menthol, tropical, citrus	None — standard pod	Everyone. Safe starting point, wide variety.
🍬 Sweet Cube	8	Candy, bubblegum, gummy, sour	3-level sweetness control via dual tank	Candy lovers. Anyone who finds disposables too sweet or not sweet enough.
🔮 Crystal Cube	10	Dessert, beverage, complex blends	Transparent pod shell	Adventurous vapers. Dessert/coffee fans.
🧊 Ice Cube	10	Fruit + heavy menthol	Maximum cooling intensity	Menthol lovers. Icy fruit enthusiasts.

🟠 Classic Cube Pods — 18 Flavors

The Classic Cube is the foundation of Off Stamp's lineup. Standard pod construction — no dual tanks, no sweetness dial — just well-executed fruit, menthol, and tropical profiles powered by Lost Mary's formulation expertise. This is the series most shops carry and the safest entry point for new users.

🍬 Sweet Cube Pods — 8 Flavors

Sweet Cube is Off Stamp's signature innovation. Each pod uses a dual-tank system with two separate e-liquid reservoirs — one sweeter formulation and one base. The X-Cube dock's sweetness button blends them across three levels. Level 1 is subtle and dry, Level 2 is balanced (recommended starting point), Level 3 is full dessert mode. This effectively triples your flavor options: 8 pods × 3 sweetness levels = 24 distinct experiences.

Important: The sweetness button on the dock only activates when a Sweet Cube pod is connected. Classic, Crystal, and Ice Cube pods are not affected by this button.

🔮 Crystal Cube Pods — 10 Flavors

Crystal Cube features a transparent pod shell that lets you see the e-liquid level and internal components. Beyond aesthetics, this series targets vapers who want flavors that go beyond standard fruit-and-menthol territory — desserts, beverages, and layered multi-fruit blends that are more complex than what you find in Classic Cube.

🧊 Ice Cube Pods — 10 Flavors

Every Ice Cube flavor is built on a fruit base with an aggressive menthol finish. The cooling intensity is noticeably stronger than the "Ice" variants in Classic Cube. If you vape menthol flavors daily, this is the series designed for you. The mint-only options (Black Mint, Double Mint, Cool Mint, Forest Mint) deliver pure cooling without fruit flavor.

Compatibility & Technical Specs

One dock fits all. Here is the compatibility matrix:

Pod Type	25K Dock	35K Dock	SW Battery
Classic Cube 25K	✅	✅	❌
Classic Cube 35K	✅	✅	❌
Sweet Cube 25K	✅	✅	❌
Sweet Cube 35K	✅	✅	❌
Crystal Cube 25K	✅	✅	❌
Crystal Cube 35K	✅	✅	❌
Ice Cube 25K	✅	✅	❌
Ice Cube 35K	✅	✅	❌
SW9000 Pod	❌	❌	✅ (SW only)
SW16000 Pod	❌	❌	✅ (SW only)

Key takeaway: Any X-Cube pod works on any X-Cube dock regardless of whether the dock was originally sold as a 25K or 35K kit. The dock is universal. SW-series and X-Cube are completely incompatible — different connectors, different dimensions.

Pod Pricing & Where to Buy

Product	VOS Price	Typical Retail	Link
X-Cube 25K Kit (dock + pod)	~$24.99	$28–35	Buy 25K Kit
X-Cube 25K Pod Only	~$13.99	Rarely available locally	Buy 25K Pod
X-Cube 35K Kit (dock + pod)	~$28.99	$32–38	Buy 35K Kit
X-Cube 35K Pod Only	~$16.99	Rarely available locally	Buy 35K Pod

The math is straightforward: after your first kit, every subsequent pod saves you $11–18 compared to buying a new kit. Over five pod replacements, that adds up to $55–90 in savings — enough to pay for an entire extra kit and still come out ahead.

Frequently Asked Questions

Can I use a 35K pod on a dock that came with a 25K kit?

Yes. The X-Cube dock is universal — it works with all Cube series in both 25K and 35K capacities. The dock that ships with a 25K kit is physically identical to the one in a 35K kit. Buy whichever pod capacity you prefer regardless of which kit you originally purchased.

Can I refill Off Stamp pods with my own e-liquid?

No. Off Stamp pods are factory-sealed and cannot be opened or refilled. Attempting to do so will damage the pod and void any warranty. When a pod is empty, replace it with a new one — that is the design intent of the modular system.

How do I know when a pod needs replacing?

The X-Cube dock's TFT screen shows your e-liquid level in real-time. When the bar reaches empty, you will also notice reduced vapor production and thinner flavor. At that point, pull the pod off and snap on a fresh one. Do not continue vaping a fully depleted pod — it risks a dry hit that tastes burnt.

Do all four Cube series taste the same quality?

Quality is consistent across all four series — they share the same dual mesh coil system and Lost Mary formulation team. The differences are purely in flavor direction: Classic for traditional profiles, Sweet for candy with adjustable sweetness, Crystal for dessert and complex blends, and Ice for heavy menthol. See our flavor guide for detailed tasting notes.

Can Off Stamp pods be used without the dock at all?

Briefly, yes. Each pod has a 100mAh internal battery that allows draw-activated independent use for roughly 45–60 minutes. But the pod cannot be charged on its own — it only charges through the dock's magnetic connection. Independent use is a short-term backup feature, not a standalone mode.

Are SW9000 or SW16000 pods compatible with the X-Cube dock?

No. The X-Cube uses a completely different connector and pod format. SW-series pods only work with SW-series batteries, and X-Cube pods only work with X-Cube docks. There is zero cross-compatibility. If you are upgrading from the SW series, you need a full X-Cube kit.

How many pods should I buy at once?

We recommend 3–4 pods across different Cube series for your first restock. That gives you variety to explore plus enough value to qualify for free shipping ($80+ at VapesOnlineShop). At moderate use, 3–4 pods last roughly 3–5 months, depending on whether you choose 25K or 35K capacity.
