1of1
Oneof one.
Numbered tees, each with its own scannable certificate.
Every shirt in the run is numbered, and no two are the same. Each one carries its own QR code at the hem: scan it and it opens that shirt's certificate.

The problem
A limited run is only limited if you can prove it.
Most numbered shirts are the same print with a different number written on. A 1of1 shirt is its own print, with its own code, and the code says which one it is.
How it works
- 01
Write it once
Your words on the chest, the shirt and the colours. The back carries the number; the hem carries the code.
- 02
Set the run
Choose the sizes and the run numbers itself, 001 upward. Change the sizes and the numbers follow.
- 03
Every shirt its own
Each shirt's number and QR are made as its own print file, and every code is scan-tested before you approve.
What you can make




Proof it's the one
- Every QR scan-testedagainst a phone camera before you can approve.
- One file per shirtso no two shirts can carry the same number.
- A certificate per shirtthe code opens this page with that shirt's number and run.
Price, minimums, lead time
Each shirt is its own print file, printed on a gang sheet and pressed on the shirt.
Questions
What does the QR open?
This page, showing that shirt's number and run: proof it's the one.
Can two shirts share a number?
No. Each shirt is made from its own file, numbered in order.
Can I add more shirts later?
A new run gets its own run code, so the first run stays complete.
