Care Instructions

  • Machine wash cold, inside out

  • Tumble dry low or hang dry

  • Do not iron directly on the print

  • Do not dry clean

Production & Shipping
Each shirt is printed to order; nothing sits in a warehouse waiting for you. Please allow 2–5 business days for production before your order ships. You'll receive tracking information as soon as it's on its way.

Shipping

How It Works
Every item is printed to order — nothing is pre-made or held in inventory. This means production takes a little longer than off-the-shelf shipping, but it also means less waste and a print made specifically for you.

Production Time
Please allow 2–5 business days for production before your order ships. During high-volume periods (holidays, new releases), production may take slightly longer — we'll flag it on the site if that's the case.

Shipping Time
Once your order ships, delivery typically takes:

  • Domestic (US): 3–5 business days
  • International: 7–20 business days, depending on destination and customs processing

Total time from order to delivery is usually 5–10 business days for domestic orders, and longer for international orders.

Tracking
You'll receive a shipping confirmation email with tracking information as soon as your order leaves our fulfillment center. If you don't see it within 5 business days of ordering, check your spam folder before reaching out.

International Orders
We ship to most countries worldwide. International customers are responsible for any customs fees, import duties, or taxes charged by their country — these are collected by the carrier or customs agency upon delivery and are not included in your order total.

Multiple Items
If your order includes multiple designs, items may ship separately depending on production location, and could arrive in separate packages on different days.

Incorrect Addresses
Please double-check your shipping address at checkout. Once an order enters production, we're unable to modify the address. Orders returned due to an incorrect address may be subject to reshipping fees.

Lost or Damaged Packages
If your order arrives damaged or doesn't arrive at all, contact us at [your support email] within 30 days of the expected delivery date and we'll make it right.

The Print
Every Oblong Box Co. design is printed on heavyweight cotton using premium direct-to-film transfer for crisp linework, deep blacks, and long-term durability — built to survive the pit, not just the wash.

Color Disclaimer
Product photos are digital mockups intended to show the design and placement accurately. Because each shirt is dyed and printed individually, actual color may vary slightly from what you see on screen — screen calibration, garment dye lots, and print batches can all cause small differences. This is normal and doesn't affect the quality or durability of the print.
