Proof and Assembly | No. 057, Unisex T-Shirt

$35.00
Select Size

Printed and ships free from US warehouses • Arrives in 3-6 days

Both start with good intentions. Both make a mess. One rises; the other always has leftover screws. “Proof and Assembly” is a poetic pairing of two modern rituals — baking bread and building IKEA furniture — that test patience, precision, and belief. This shirt is for those who measure twice and still improvise. For those who let things rise, even if a little lopsided.

A text-based design pairing “Proof and Assembly” with two subtle icons: a loaf of bread mid-rise and a wonky Allen wrench.

Inside the collar: “Chaos becomes structure” | “混沌は構造になる” — a quiet reminder that what begins messy can still become whole.

We exclusively use Bella + Canvas 3001 blanks for our minimalist t-shirt designs because they deliver the perfect balance of comfort and durability. This premium unisex fit feels soft and effortless — the kind of quality shirt you forget you're wearing while it gets better with every wash.

We choose Bella + Canvas 3001 because it holds shape without clinging or stretching out, provides superior ink absorption for crisp long-lasting designs, features pre-shrunk and side-seamed construction, and is responsibly sourced from ethical factories.

Material specifications: Solid colors are 100% Airlume combed and ring-spun cotton. Ash is 99% cotton, 1% polyester. Heather colors are 52% cotton, 48% polyester. Athletic and Black Heather are 90% cotton, 10% polyester. Heather Prism tones are 99% cotton, 1% polyester.

All shirts are ethically manufactured in Nicaragua, Mexico, Honduras, or the United States, ensuring quality craftsmanship and responsible production practices for every minimalist design we create.

We create each product only when you order it — zero waste, zero excess inventory. Our made-to-order process takes 3–4 days before shipping, but this thoughtful approach helps us eliminate overproduction and reduce our environmental impact.

Rather than contributing to fashion waste, every ichinichi design is printed fresh specifically for you. No mass production, no unsold inventory ending up in landfills. It's sustainable fashion by design — slower, more intentional, and better for the planet.

Your product doesn't come from a warehouse pile; it's created with purpose, one order at a time.

Yes! We ship worldwide with free international shipping. Orders ship from the closest warehouse to you - US orders from the US, EU orders from the EU, etc. Allow 2-5 business days for production, then shipping time based on your location (US: 3-6 days, International: varies by region).
