Buying more than one?

Each edition still available above has an International · +$25 shipping button — worldwide, flat $25 (US orders ship free). 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.
