IN STOCK · SHIPPING NOW

Order yours. Ships in 3–5 business days.

Every stick is flashed, tested, stickered, and sealed in a tamper-evident bag by us — then shipped tracked ($5 in the US) in a plain unbranded mailer. Nobody in the delivery chain learns what’s inside.

Compatibility, in one line: the bootable editions need a Windows PC or Intel based Mac with a processor from 2012 or newer. The for Mac editions are for Apple Silicon Macs. Chromebooks, phones and tablets are not supported.

Buying more than one?

Each edition still available above has an International · +$25 shipping button — worldwide, flat $25 (US orders ship for $5). Same stick, same guarantees. Use the quantity selector on the checkout page to order up to 25 sticks at once — the $25 international shipping is charged once per order, not per stick. Ordering separately, one at a time, pays it every time. Any customs or import duties are the buyer's responsibility, and we can't ship to countries under US sanctions.

The order terms, in plain words

  • Timing: orders ship within 3–5 business days; you get tracking the day it leaves. If we slip, you can cancel for a full refund at any time before shipment.
  • Independent review first: no stick ships until the entropy path — the code that makes your randomness — has passed independent security review. That review is already arranged. It’s a launch gate, not a promise.
  • Returns: 14 days, unopened tamper seal only, minus shipping, handling, and a repackaging fee. A broken seal voids return — for your protection as much as ours.
  • Privacy: plain mailer, no crypto branding in transit, and we keep only what fulfillment requires.
