Crystal Cube · 35,000 puffs · Splash Device + Pod
The X Cube Crystal 35K Kit is the largest-capacity device in the current Off Stamp lineup. It ships as a two-piece assembly: a clear-chassis Splash device and a pre-filled 35,000-puff Crystal pod. Once the kit pod is finished, you keep the device and swap on a Crystal 35K refill pod — the same 20-flavor range at $21.99 instead of $23.99. The Crystal device only accepts Crystal pods; it is not cross-compatible with the 25K Cube pod.

Crystal and Classic are two parallel product lines, not a generation upgrade. The Crystal device pairs with a 35,000-puff pod and 20 Crystal-exclusive flavors; the 25K Cube device pairs with a 25,000-puff pod and a much wider flavor catalog split across Classic, Sweet, and Ice editions. Crystal pods will not snap onto a 25K device and vice-versa, so pick the line that matches the flavor family you want. If you're new to the X Cube system and you want maximum runtime per pod, the Crystal 35K Kit is the right place to start. If you want the broadest flavor selection on day one, look at the X Cube 25K Kit.
The Crystal lineup is heavier on fruit and ice profiles than the Sweet edition is, with a small group of bakery and beverage flavors mixed in. The exact roster on the device:

The pod is sealed at the factory and is not refillable with bottled e-liquid — once the wick runs dry, the pod is finished and goes in the trash. The device, however, keeps running indefinitely as long as the battery holds a charge. Order a Crystal 35K replacement pod, snap it onto the device, and you're back to 35,000 puffs at refill-pod pricing. The device holds its USB-C charge across pod swaps.
Every Crystal 35K Kit ships with a tamper-evident QR seal printed on the carton. You can verify the seal on our product verification page before opening — if the seal is broken on arrival or the QR code does not validate, contact service@offstampvapeusa.com with the order number for a free replacement. Devices that arrive defective or stop working within 14 days are replaced under the standard Off Stamp warranty; the full process is on the Refund & Returns policy page.
No. The Crystal pod uses a different connector and chassis dimension than the 25K Cube pod. The two product lines run in parallel — choose the device that matches the flavor family you want. We get this question often enough that the FAQs page has a longer comparison: read the full FAQ →.
The 35,000-puff rating is the lab number with a controlled draw. In normal daily use most customers see two to three weeks per pod. Heavy users will finish faster; light users can stretch a single pod past a month.
The kit includes both the rechargeable device and a pre-filled pod, so you're paying $2 extra for the device — a one-time cost. Once you own the device, every subsequent pod is $21.99 with the same 35,000 puffs and same 20-flavor selection.
The QR code on the carton links to a record in our authentication database. A valid QR confirms the unit was packed at the licensed Off Stamp facility, has not been resealed, and is the genuine article — not grey-market stock. Verify before opening on the product verification page.
The Crystal 35K Kit headlines the premium tier on the Off Stamp Vape store — pair it with a Crystal pod from the flavor catalog, or find one nearby with our near-me finder.
Each flavor has its own page — pick one, then choose kit or pod.
Bought the Crystal 35K Kit two weeks back to replace a smaller disposable. The clear chassis is a nicer look than I expected, and the 35K pod really does last — Crystal Berry has been my daily, lasted me about ten days of moderate use. Charge port works fine with any USB-C cable I had around. Pod swap is foolproof. Will reorder the refill when this one taps out.
